I'm using the current release of the Play framework. After having created a new project via activator new foobar, I tried to import it into IntelliJ IDEA (with installed Scala plugin) by importing the project's build.sbt file.
IDEA/SBT then downloads the dependencies but is always stuck here (even after hours nothing happens):
SBT: [info] downloading http://repo1.maven.org/maven2/org/scalaz/scalaz-core...
Any help is appreciated.
I have not personally experienced that kind of hanging behavior, but here are a couple of thoughts.
I see that this library is about 1MB. (I'm not sure on the exact version, but I picked a recent one: http://repo1.maven.org/maven2/org/scalaz/scalaz-effect_2.11/7.1.0). Are you on an unusually slow connection? Others have reported the hanging when downloads are slowly taking place. See https://stackoverflow.com/a/12605068/2308858.
You can try clearing your ~/.ivy2/cache folder (this has fixed things for me before). If on Windows look for .ivy2/cache near your home folder.
I've noticed that sometimes SBT does not give insight into what it's doing, often because it is suppressing otherwise helpful output. Check out http://www.scala-sbt.org/0.13.5/docs/Howto/logging.html for some options on how to see more details or change the logging level.
Update: See second comment on original question for additional details.

Really basic question here but this has always stopped me from using any JetBrains product, but here I am trying once again. I also have the same issues with CLion but that will be for another time and hopefully I can figure it out based on some feedback from this post.
I need to set up my environment in IntelliJ. Nothing special. No build tools. Currently I just run my school projects using
javac Main.java
java Main
This has gotten me so far but I really want to use IntelliJ tools to their full capacity.
I want to be able to set break points and step in and out of my code in their debugger and all the other nice tools that come with running my code through IntelliJ
Every get started tutorial that I have watched on YouTube or from JetBrains themselves already has a basic build configuration set up to run your basic "Hello World" application and that is what I think I need. Just compile my java files into classes and run/debug them.
This is what the run configuration icon in the IDE should look like
And this is what mine currently looks like
I have set many different JDKs to go along with my projects but none of them seem to get the tools I need set up in the IDE. I have even let IntelliJ download one for me and set it up itself to see if maybe I downloaded and installed it wrong and IntelliJ maybe wasn't recognizing it.
This picture below is showing the project structure for an application that I let IntelliJ download a JDK for and set it up itself
So if someone could help me that would be fantastic. Links to videos, blogs are welcome even though I know that isn't the convention on this forum but I think that would be sufficient for my situation. Thanks in advance!
---Update---
I have found that if I create a project in IntelliJ that I get all the default configurations that I need. The problem is when I need to get a project from VCS that I am not getting any of the configurations that I need to run/debug my program in IntelliJ.
The easiest solution here would be to click the green play button next to your main method, on the left where line numbers are displayed.
Intellij will configure a default java run configuration for you. It will be displayed in the menu for later use, like in the screenshot you posted, after your first run.
You can also create one using the to menu: Run > Edit run configuration to add some more options like arguments, environment variables (that only apply for the run config), etc.
A good starting point would be the Intellij help page on that topic. This help pages are always a good start and you find comprehensible instructions there on every topic.
Another good resource is the Intellij by JetBrains YouTube channel. This video about debugging shows both ways I described above. They have lots of quick tutorials about lot of features, like code generation or build tools. Check out the channel's playlists for specific topics.
Update
The problem with the already created project is that the default/ folder is not marked as source folder. You can do that by File > 'Project Structure...' and set the default/ folder as Sources:
The cause for intellij not recognizing this is because you didn't use a folder structure like the one of maven.
For source code:
src/main/java
src/main/resources
and for tests:
src/test/java
src/test/resources
If you set it up that way IntelliJ everything works as expected. I created a pull request to your repo. If you check out the branch, IntelliJ will setup everything correctly automatically.
Below you can see the output I get when I try to run npx react-native run-android. It suggests some options to try in order to further pinpoint the problem, however they don't work with the aforementioned command so I assume that they are related to a gradle (just an educated guess).
I know ZERO about gradle; I have just seen the name here and there and in the output shown below. So please keep that in mind when you answer. If I need to learn how to run some gradle command(s) directly, please be as verbose as possible in your answer.
The project was working fine just a bit ago, but I wanted the ability to force portrait mode for certain screens but without configuring my entire app to always have to stick to portrait mode. So I found what looked to be a solution in the react-native-orientation-locker module. I installed it with yarn and then proceeded to update files as directed: https://www.npmjs.com/package/react-native-orientation-locker.
After updating the appropriate files, I got an error that suggested axios was the problem. I uninstalled and reinstalled axios. After that didn't work, I proceeded to undo all the file changes I had just made. Then I uninstalled the react-native-orientation-locker module.
To my knowledge, I have undone everything I did between the time the project worked and stopped working.
Sadly, I had not put this into source control yet (a mistake I won't make again), so I can't revert.
Where to go from here?
Problems like this are hard to pin point. What you can do is open the android project in android studio and see the logs as the project is being assembled. I assume you do not have much knowledge about android either so you might need some senior resource to help you.
What I usually do in this case is open android studio and if I am lucky enough, it tells me which file has an issue and I go to the file and do what android studio suggests me. Some times it fixes the problem and sometimes it doesn't.
Another thing I would like to mention is that the documentation of the package you are using is important to follow. I assume you did that already but I would suggest to review it narrowly and closely.
Another guess I can tell you is try to go to your-project/android/build.gradle and over there, you'll see something like this in the start. The package you are using mentions something about target SDK 27. I think you should check that out too. May be it helps
Lastly I would say always use source control while working with react native. It can easily blow up at any time so you should always have a safety net to fallback to :)
As an daily IntelliJ user you usually concentrate on the projects you are working on and IntelliJ is just a tool. You are not willing to dig into tool's problem itself. But this is what is forced on you by default after IntelliJ installation on MacOS and opening relatively big project(most of the projects nowadays are huge and have thousands of files and use numbers of IntelliJ 3rd party plugins).
Here is a minimal list of actions. IntelliJ must have set MORE RAM to be used by default.
Read: https://intellij-support.jetbrains.com/hc/en-us/articles/207241085-Locating-IDE-log-files .
From IntelliJ open Help / Show log in Finder and open idea.log file with Console.app; In Console.app press "Reload" and "Now" buttons to track "live" what IntelliJ is doing.
If in logs of IntelliJ you find that some of the plugins exit with fatal error, you just uninstall those plugins. For me the one that failed to the moment of this answer was "BashSupport" as example.
Start Terminal.app ; Run command: open -a TextEdit /Applications/IntelliJ\ IDEA.app/Contents/bin/idea.vmoptions ; Change options in idea.vmoptions file to:
-Xms1024m
-Xmx2048m ; Read https://www.jetbrains.com/help/idea/tuning-the-ide.html to see how you can tune IntelliJ for your project. This step is handy when your IntelliJ app doesn't start at all and you want to change properties in a global way.
From IntelliJ open Help / Edit Custom Properties.... Here you can set same properties that will override global and will work only for current OS user.
Also there is also a possibility of underlying OS to do it voodoo magic so the IntelliJ won't work as it should like here - https://intellij-support.jetbrains.com/hc/en-us/community/posts/360000398280-IDEA-Ultimate-2018-2-Unable-to-save-settings-Unable-to-create-file-Windows-10
Make sure your project build output for *.class files is set. Read: https://intellij-support.jetbrains.com/hc/en-us/community/posts/360000000584-Build-does-nothing . In my case when IntelliJ started project build it terminated without warnings shortly after.
Finally in my case none of 6 steps above solved the issue so I found this read: https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000532044-IntelliJ-cannot-build-projects . Basically try reinstall IntelliJ from original distribution again.
I know that you must read https://www.jetbrains.com/help/idea every time you install a new version of IntelliJ, but why not to add some consistency into configuration process of the main java process that runs IntelliJ itself? You can ask how much ram to use during installation of IntelliJ and explain why it is so. Then Help digging won't be necessary in the first place for devs who fed up with changing those default settings that will be always more than 700MB. I think for most devs out there it is at least 10x of that. I bet what makes most devs mad about this is not the fact that you need to do some options changing, but where those options are depending on OS plus the fact that you simply forget why IntelliJ app just exits while you are doing a debugging of your own app. I bet this problem makes us mad since first java based IDEs appeared. User-friendly is the key here and explicit reminders within the app itself would help.
In IntelliJ, I have to manually import Flutter packages at the top of the file in order for auto-complete to work elsewhere in the file.
I was rather hoping I could start typing something (in a method) and IntelliJ would search my pubspec.yaml and locally within my project and suggest classes I might want. If I selected something that wasn't already imported, it should import it for me.
This basic functionality is available in many other languages and IDEs, so I'm wondering if I've got something misconfigured. I'm using IntelliJ 2018.2 with the latest Flutter and Dart plugins installed.
This is a known issue.
For performance reasons the DartAnalyzer was built to only load libraries that were imported anywhere in the projects code already.
The overall performance of DartAnalyzer was improved a lot since then and it would now allow to provide better suggestions, but it seems there weren't enough resources available yet to get it implemented.

I had a working sbt based project. After some small change that I can not specifically identify all the sbt files are having object resolution issues (see screenshots).
I tried the following:
sbt refresh
project rebuild
reimport project
These did not work.
Then I started going farther afield to resolve the issue. I copied the *.sbt files from another project on top of the ones in this project. Still no dice. Now I do not have time presently to actually completely destroy, rebuild the project from scratch - and in any case that does not lead to any insight on the root cause here.
Has anyone experienced this issue - and any suggestions on remedies/workarounds?
Update I finally tried
sbt gen-idea
even though this project was **not ** built that way.. It did make a difference: at least the crazy errors went away. But now a different set of problems arises: the assembly and packaging imports are not being resolved (see LAST screenshot). But this seems a bit more healthy at least .
Following screenshot is after running sbt gen-idea. Situation has improved but now get assembly/packaging import errors.
Another update
OK, I have quit and restarted IJ and things are finally back.
So the objective changes that I made:
sbt gen-idea
stop/restart IJ
This is feeling like magic incantations here .. Not a solid process.
A sort of a workaround could be to upgrade to the latest EAP of IntelliJ IDEA 13.1.3 build 135.909, released on May 23rd, 2014. It comes with more sophisticated Scala plugin that is much clever than the previous versions and hopefully could help here and there.
