Just installed version 2016.2.5 of the Community edition of IntelliJ and then installed the Go plugin from:
https://plugins.jetbrains.com/plugin/5047
I followed the wizard for creating a new project but when I come to run a simple hello.go file I get a "Main file is invalid" in the "Run Configurations" dialog.
Does anyone know of a step by step guide to setting up and running the simplest of Go projects?
I've tried GoClipse and now IntelliJ and for both the user documentation is absoluetly crap. It's always the same: they spend ages developing this stuff and proide zero useful documentation!
Thanks

I use the plugin with WebStorm, and it is quite an improvement over previous Go IDE attempts.
The issue you run into is quite simple. The auto-generated code does not have the package set to main. For that reason, the main file is invalid. You need to manually set the package to main, and add a function called main.
My steps to ensure a working Go development environment and set up a new project are:
Install Go
Set GOROOT environment variable to Go installation, e.g. /usr/local/go
Create a go directory in your home folder, and set GOPATH to it.
Install IntelliJ + plugin
Create a new Go project in a subfolder of $GOPATH/src
Set the Go SDK in IntelliJ
Create a main .go file and make sure package name is main, and a main function exists.
Now you can create a proper Run configuration.
For me, this works quite well, including debugging and running unit tests.

I'm using IntelliJ with the go plugin to write my application.
version of Go: go version go1.7beta2 darwin/amd64
Operation system: OSX El Capitan 10.11.5
Intellij Version: 2016.1.3
Go Installation Location: /usr/local/go
Go Pkg Location ($GOPATH): /Users/ufk/projects/go
when I open terminal, browse to my application's main source file, and type go it compiles it properly without any errors.
but when I try to Run the program using Intellij, which also compiles it, i get the following error:
/usr/local/go/pkg/tool/darwin_amd64/link: cannot open file /usr/local/go/pkg/darwin_amd64/github.com/codegangsta/negroni.a: open /usr/local/go/pkg/darwin_amd64/github.com/codegangsta/negroni.a: no such file or directory
lookgs like it's looking for the negroni package in the location when I have go installed, and not where I the 3rd party packages are installed according to $GOPATH. My project is configured to use $GOPATH, and the real time error of the intellj editor doesn't complain about packages that are not installed which means that Intellij does check the $GOPATH variable.
so what am i missing ?
thanks
update
Hi :)
I noticed something new... I have 2 go projects, one of them is the JSON Api Server, and the other is for the web server.
The project that is causing issues is the Api Server.
now, the web server also uses and imports negroni, but the problem occurs only on the Api Server Project.
so I decided to go wild and delete the .idea and iml file from the Api Server, reopen it with intellij, and see what happens... welp, what happens is that now it complains about a different module.
/usr/local/go/pkg/tool/darwin_amd64/link: cannot open file /usr/local/go/pkg/darwin_amd64/github.com/jingweno/negroni-gorelic.a: open /usr/local/go/pkg/darwin_amd64/github.com/jingweno/negroni-gorelic.a: no such file or directory
the thing is.. that my web server project also uses negroni-gorelic and things are fine!
I tried downgrading go from 1.7beta2 to 1.6.2, deleting the content of the modules ($GOPATH/pkg and in src directory github.com and golang.org)
then I got all the modules again.. tried to compile with intellij and the results are the same.
so... hope this helps to further investigate the issue.
I have a Go program which I'm working on in IntelliJ IDEA on a Windows machine. The program's structure is a little unconventional (don't want to go into detail here as its besides the point) because of which I first have to compile the program using the following command:
go build -o cli.exe
And then I can run cli.exe directly in the command prompt.
But how do I configure the run configuration in IntelliJ IDEA so that it doesn't mind running a Windows executable ? Because if I try to tell it to run an EXE file as it's run configuration, it gives me error "Main file is invalid"
How do I solve this ?
Make sure you have a file name (not a folder name) in field File on Run/Debug Configuration window (In IntelliJ IDEA go to menu Run->Edit Configuration...->your_configuration). That was my case.
You may be able to install the Bash plugin on Windows, then create a run configuration using the Bash plugin, and just run your executable from a script.
Create a Go Application run configuration and that should work. You can choose to run either a file or a package. If you would share more details then the answer would be more complete. If you still have an issue with this, please open an issue to the bug tracker and I'll be able to help out (please follow the issue template there).
I made changes to Intellij Community Edition (ce). I can compile and run those changes from within the IntelliJ editor. That launches a second instance of IntelliJ ce which is running from classes containing my changes. What I want to do is just run those changes without having to first load the source, compile and run from within IntelliJ.
Netbeans made this easy by just producing an executable as a result of the build. With Intellij, it's not at all clear what has to be done. I have tried the following-
using the Run configuration Intellij itself uses to run the altered classes- this includes setting the working directory , main class, vm options and classpath. Actually, this doesn't work for reasons unknown to me.
on someone's suggestion, running dist.gant in build. This blows up with very many errors which are not helpful (no class def found errors which indicate some confusion on Intellij's part on classpaths somewhere)
Running WinLauncher.exe under bin gives the error message that it can't find VM options file (although it's in bin, (and also for good measure under bin/win with the other files which are co-located with vmoptions in the intellij directory structure for Intellij proper. )
ALl this is just harder than it should be. The solution is to provide an executable as a result of the build and place it in a predictable location.
Has anyone ever actually DONE what I am trying to do- make changes to the community source then use the resultant editor not as a project you're working with in IntelliJ but as the Intellij editor you're working through?
FOLLOW UP
User60561 had the correct answer. Just to mop up the details, in artifacts, there is a compressed file (win.zip for Windows, mac.zip for Mac etc.). In order to run your snapshot, you have to unzip this archive (after which it will have the same name, minus the zip extension) then go into folder "bin". There you'll see two executables: idea.exe and idea64.exe, for 32 and 64 bit versions, respectively. Clicking on these runs your snapshot.
Adjusting contents of the files idea.exe.vmoptions and idea64.exe.vmoptions lets you set the VM parameters to suit yourself, typically people might want to give the VM more memory through the -Xmx value.
It seems straightforward:
To build the distribution archive of IntelliJ IDEA Community Edition, execute build.xml Ant build script in the root directory of the source code. The results of the build execution can be found at out/artifacts.
https://github.com/JetBrains/intellij-community#building
So download ant, and run ant in the directory that you have it stored in. Make sure to use the commandline to launch ant in order to make sure everything is working correctly.
Initially execute getPlugins.bat/sh, then:
Use update.bat/sh according to it's instructions
Or
Click on: Main Menu | Build | IntelliJ IDEA CE build
Copy content of intellij-community\out\deploy (lib, plugins folder) into existing IJ installation (sometimes it is better to delete existing folders if they contain older dependencies or when the installation was of Ultimate version)
I am a new scala user and am having problems getting a development environment functional.
I downloaded the typesafe activator which launches an editor in a web browser and was able to run the akka actor tutorial script fine.
However, I have set up my intelliJ scala/akka environment, and when copying the same sample code to intelliJ, I am getting compile errors. I have added akka 2.2-M1 via maven to my project.
Initially when I copy
import akka.actor.{ActorSystem, Props, Actor, Inbox}
the last "Inbox" library is highlighted in red, and on compile I get "Error: object Inbox is not a member of package akka.actor. It suggests that I add akka.actor.dsl.Inbox. When I do that the import is greyed out because it is "not implimented", and get a compile error further down in the script when I go to implement inbox. It says "
not found: value Inbox
val inbox = Inbox.create(system)
"
What am I doing wrong? Thanks!
I would recommend you use sbt and then use the gen-idea plugin to create your intellij project.
You'll need to re-run gen-idea every time your dependencies change - intelliJ currently won't automatically discover and resolve managed dependencies for you.
here is the plugin with directions.
https://github.com/mpeltonen/sbt-idea
also, as a professional I would recommend you use the sbt console for most of your tasks.
Ctrl-tab 0 will let you hop over there without touching your mouse.
Escape brings you back to the code editor window.
You can run sbt ~test to test on change to your files etc.
Note you may need to change focus off of intellij for it to save the file in memory if you're use ~test
I managed to resolve the same issue by adding the following library from the Maven repository
com.typesafe.akka:akka-actor_2.10:2.2-M3
to File -- Project Structure -- Libraries
Ok, so I'm working on a project using IntelliJ and trying to take advantage of its cucumber functionality. I've not worked with the java flavour of cucumber, but IntelliJ seems to want the step definition files in a specific location, relative to the feature files.
I found this: how to define step definitions location for cucumber in intelliJ 12 and other sources that pointed me to been able to add the "glue" property of my run configurations which tells cuke which package to find the step file. So I am at a point where I can run my tests via IDEA. BUT I need to set this every time I run a new test, as Ctrl+Alt+F10 or right click+run test will not start the test with this flag. Also, the ide support is screwed as IDEA doesn't know where the steps are, it doesn't auto complte or Ctrl+Click navigate to steps.
Is there a way to the the IDEA project to always look for steps in a given package both when running the tests and for its auto complete?
Creating self answer for others who might have this problem. My project did not have the steps marked as test source root, and although I DID do this, it was not until I closed and reopened my project that they were picked up. So a simple restart was my answer.
You can set the glue location globally by opening "Edit Configurations -> Defaults -> Cucumber Java -> Glue" and add the package names.
(IntelliJ 12.1.4)
Go File->Settings--> plugins
Install Cucumber for Java plugin
Then you can manage cucumber plugin as shown below
This should redirect you to step definition when you click your test.
Hope this helps
IntelliJ supports a plugin for Cucumber-Java/Groovy. Installing this plugin will enable the navigation from Steps mentioned in the feature file to the Step Definitions.
And after creating the Step Definition, navigation is easily possible
I go in EditConfiguration, Glue section and i put the path from the package above and the package where is your class for steps, ex:
CucumberFramework.stepsDefinitions
It is really nonsense :) but in in my case when IDEA refused to add steps definition automatically due to some plugins installed, e.g. Cucumber for Scala and suggested deleting them that i cant since i need them in other project. So, long story short, to add (Create step definition) you need to create Class in 'glue' dir and some fake Cucumber implementation, build one more time and it resolved my issue.
Background:
When I use IDEA 2018.2
And Java 8
And Cucumber info.cukes:cucumber-java:1.2.4
#When("^I created a Class and put there fake step implementation$")
#And("^I run gradle build one more time :)$")
#Then("^This Class will be able for me from the feature file by ALT+ENTER as usual$")
#And("^It resolved my issue when I was not able to automatically generate step definition$")
