I've got a similar to this post problem, the only difference is that it's opposite. :D I've got only jdk (using jre from jdk package). When I add this in SDKs section, I suppose IDEA should load all the necessary libs from jdk_path/jre/lib, but it doesn't.
What's strange is that the first time I add jdk classpath settings are just great.
This looks more like a bug. Whenever apply key is pressed, default jars that were added to classpath earlier are just gone. Pressing OK in stead of Apply is a valid workaround. This should be reported in a bug trace system.

firstly, I want let you know how useful this community is for me, I was stuck on an error
`Error: JavaFX runtime components are missing, and are required to run this application`
and thanks to this answer I actually solved: link
However I've a couple of questions. I noticed that IntelliJ doesn't change the configurations (Like set the VM option and pick the right library for the javaFX project), so each time I've to create a new JavaFX11 or 12 project I've to being throw all the manually settings again.
There's a way for set a "default behaviour" for the IDE ? It's really cumbersome.
The second question is, how I can use all the beautiful framework that the developer community offer for JavaFX? I've seen on openjFX a couple of interesting framework like TilesFX or CalendarFX but there's no information on how implement them on my IDE neither on GitHub nor here.
I have seen that most of them uses Gradle files, but honestly I don't have the faintest idea of what this kind of file does and how implement it on IntelliJ. Thank's to everybody.
Run the project with a more recent JDK like JDK11, for example.
If it does'nt work, you probably forgot to change the JDK of your builder in IntelliJ!
Open the settings and follow the path as bellow:
FOR MAVEN
FOR GRADLE
I'm using Mule Server 3.8 EE which brings commons-lang 2.4 with it. A third-party library in my project needs commons-lang 2.6, because it uses a method that was introduced in this version.
So when I just start my application, I get a java.lang.NoSuchMethodError
Is there a way to update the dependency in the runtime? What I tried so far:
including commons-lang 2.6 in my app -> no effect, the one from the runtime is picked up first
replacing the jar directly in the runtime -> errors in studio, that the 2.4 jar is missing
so maybe i am late BUT -- this is your answer. Add the libraries that are newer in the jar distribution to the Build Path. Under Java Build Path screen you should see the libraries listed. I needed to use Apache http-client 4.5.6 and that's very interesting because it brings with it a lot of other dependencies, so your question was VERY relevant. The solution is to rely on JAVA (and not mule -- oops Anypoint or whatever) conventions and make sure the JVM loads my class files first. Then, it won't load the old ones from mule's jar. And so I went to the tab Order and Export, and moved Mule to the bottom. This simple, trivial change makes it work. I think if we would work with command line and vim, we would all know this. But all the IDE gui and everything else makes us forget the simplest things. Please use it in good health. :)
In a new project in IntelliJ I have set up a Java 8 JRE/JDK and language level 8.0.
But for some reason, the IDE cannot find java.util.Optional. The project compiles and works just fine (from within the IDE, too) but code completion does not work.
Any ideas? I'd like to ask a few other users before creating a ticket on their bugtracker...
I finally figured this out. For whatever reason, there was an entry for java.util.Optional in the exlusions under Editor, General, and Auto Import.
Removing that did the trick. No idea how or why it ended up being there. Doesn't sound like anything I would want to do.
Stupid IntelliJ.
I have a SpringBoot project which worked just fine. Then, the next day, when I want to run it, I got this error:
Caused by: java.lang.Error: Unresolved compilation problem:
The type java.util.Optional cannot be resolved. It is indirectly referenced from required .class files without changing anything!
I cleared IntelliJ cache.
Although it was a maven project it was already using JDK8,
I have changed the Project Settings, and said (again) to use JDK8,
Maven re-import, Cleaned the project, Build->Rebuild project, and it magically worked again
I had a similar problem in ubuntu. For me the problem was that I used JDK1.7 and when I changed it to JDK1.8 everything worked just fine.
Now, that makes sense, as Optional is something that was introduced in JDK1.8, before that the concept was exists only in Guava: http://onelineatatime.io/optional-guava-and-java-8/
Ran into the same problem (in IntelliJ 2017.2.7) and solved it like this:
Project Structure->Modules->Module SDK and there change it to 1.8
I've also first set Java compiler to 8 and Project Structure->Project->Project SDK and Project language level also set to 8 without success. In the end, the step I described finally fixed it.
I ran into this recently. The issue was related to my Project SDK setting. Didn't have to clear any caches.
The issue shows with my Project SDK set to 1.8 (1.8.0_202). The issue was fixed by changing it to 11 (11.0.6). Also confirmed that the issue reappears when I switched it back to 1.8.
In java 8 some functions of Optional class not supported such as isEmpty, ifPresentOrElse, or, stream, orElseThrow. You should check whether you use them or not. If you want to use these functions you can use java 11.
as already described in title, i'm not able to open the project structure dialog window in intellij anymore.
neither the shortcut (Ctrl+alt+shift+s) nor the menu element under File -> Project Structure nor the little button in the upper right corner do work.
Clarification: Menu element :
This "bug" occured suddenly as I wrote a web (vaadin/maven) project and tried to set up glassfish, where i often had to switch to the project structure dialog.
Since the first occurence i wasn't able to fix it by restarting intellij or switching projects.
This also happened on my laptop running the same intellij and windows version (Ultimate 13.0.1 Build: 133.331 on Windows 7 x64)
i appreciate any help!
This also happened to me, but removing new plugins etc didn't help.
Nor did nuking my project and rebuilding it from scratch.
In the end I deleted all caches, restarted Intellij and at last I could access the project settings again! By the way, I'm using Intellij 11.1 - mainly because I can't get 13 to start up, but that's another story
Your log shows that it is a bug in IntelliJ IDEA - they are trying to create file passing null pathname. Try to delete project files and reopen project from scratch (maybe you've lost some file) - if it won't help then you should create an issue here: http://youtrack.jetbrains.com/ - You can even copy-paste text from your question and attach stacktrace
I had the same issue...upon further inspection in the log dump...I noticed the following:
ERROR - llij.ide.plugins.PluginManager - com.intellij.openapi.fileChooser.FileChooserDescriptor.setTitle(Ljava/lang/String;)V
java.lang.NoSuchMethodError: com.intellij.openapi.fileChooser.FileChooserDescriptor.setTitle(Ljava/lang/String;)V
at com.jetbrains.python.sdk.PythonSdkType.getHomeChooserDescriptor(PythonSdkType.java:247)
Disabled the latest Python Plugin and restarted and everything is working normal again.
I remembered I had recently update my python plugin and am not using it presently so I was able to disable it without issue.
Hope this helps someone else.
This also happened to me. The comment above helped. I had just added some plugins. Disabled them and it started working again. Not sure exactly which one because I disabled all 4 -- Bean Validation Support, Bitbucket, Jelastic Cloud Platform Integration, and Quick Notes.
For me it has been resolved by switching off FindBugs plugin and restart IDEA. So Project Structure is available for me now.
One of the plugins might be causing it. To disable a plugin, go here:
You'll know for sure if a plugin is bad if you see this Exclamation picture:
Clicking on it will bring up a pop-up. To disable the plugin, click on this:
For me it got resolved just by restarting the intelliJ IDEA. I'm using intelliJ IDEA Ultimate 2018.1 edition.
I have installed jdk-8-ea-bin-b82-windows-x64-21_mar_2013 and IntelliJ IDEA 12.0.4. The strange thing is that I can't find java.util.stream in the intellisense provided by the IDE. I tried to compile either using the IDE or using the notepad and the compiler but it gives an error complaining that java.util.stream cannot be found! I have already set the module settings to use Java8 jdk. Any ideas about this problem?
I had the same problem with Netbeans. It seams that older versions of JDK 8 are not correctly packaged.
I had the same problem with b84, but I installed the build b116 and it is working properly.
PS: I think this is what #rmuller said in his comment
To change the JDK version, go to File --> Project Structure, and make sure both Project SDK and Project Language Level are set to JDK 8.
(I know you said you set the JDK level in the modules already, but I'm posting this here because there is relatively little information online on how to do that. Even the IDEA documentation on this issue doesn't mention it!)
Try to download from: http://jdk8.java.net/lambda/ to have lambda and stream support
As #rmuller pointed out there was no streams in the early release version that I have downloaded 5 years ago when I asked the question. Short while after I asked the question a new release was available and it contained the streams support.
YOU CAN SET PROJECT SETTING IN MODULES
THE LANGUAGE LEVEL SET 8-LAMBDAS
enter image description here
BEACUSE THE DEFAULT LANGUAGE LEVEL IS 7 -Diamonds
