Error while Running IntelliJ after Community source code build

Hello,

Please check related issue on YouTrack: https://youtrack.jetbrains.com/issue/IDEA-299247/intellij-community-throws-exception-on-launch

Hi,

Thanks, I was able to change the VM options and Run from the IntelliJ IDEA Ultimate Edition. 

Will I be able to run this without using the IntelliJ IDEA Ultimate Edition as a standalone IDE?

Do you need to run your modified Community Edition? Then you need to create installation package:

"To build installation packages, run the installers.cmd command in <IDEA_HOME> directory. installers.cmd will work on both Windows and Unix systems."

Thanks a lot for the info. It worked :)

You are welcome!

Hi, need one more info.

I had created installation package for IntelliJ IDE by using the "Build IDEA Community Installers (current OS)" run configurations.

Will the same run configuration create installation packages for PyCharm as well or is there a different approach?

I am asking because now my /out/artifacts path does not have the installers for PyCharm.

There is installers.cmd file in "python" folder.

Thanks for the quick reply.

I ran installers.cmd.

It says "Build Successful", but also throws a fatal error.
The /out/artifactory/ path still does not have the PyCharm installers.
I have attached the last part of the build logs.

ERROR occurred, see the output above

Hi, in continuation to the above comment..

Should I run the installers.cmd with arguments?

Please try to use IDEA script but change class for PyCharm.

Also you may try Ant script:

```

To build the distribution archive of PyCharm Community Edition, execute build.xml Ant build script in this directory. The results of the build execution can be found at out/artifacts.

```

When I execute the build.xml Ant build script, I am ending up with the same error mention in my previous comment https://intellij-support.jetbrains.com/hc/en-us/community/posts/10011312823442/comments/10177163596562 

Could you please elaborate a bit on your suggestion 

Please try to use IDEA script but change class for PyCharm.

To build IDEA installation package this script is used:

```

exec "$root/platform/jps-bootstrap/jps-bootstrap.sh" "$@" "$root" intellij.idea.community.build OpenSourceCommunityInstallersBuildTarget

```

but for PyCharm "intellij.pycharm.community.build PyCharmCommunityInstallersBuildTarget" should be used.

So just change it in IDEA build script and try to run.

I did not understand if you are asking me to create a run configuration or change the installers.cmd content.

However I created a kotlin run configuration as below:

Main class : PyCharmCommunityInstallersBuildTarget

VM options : 
-Djdk.module.illegalAccess.silent=true
-Didea.platform.prefix=PyCharmCore
-Didea.config.path=../config/pycharm
-Didea.system.path=../system/pycharm

Working directory :
C:\Jay\codebase_general\JetBrains\221_Final\intellij-community

Use classpath of module :
intellij.pycharm.community.build

Shorten command line :
@argfile (Java 9+)

And to add on, with the run configuration mentioned above, I got the following error

java.lang.RuntimeException: java.lang.RuntimeException: java.nio.file.NoSuchFileException: C:\Jay\codebase_general\JetBrains\221_Final\intellij-community\..\build\plugins-autoupload.txt
       at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

Please let me know if I have to make any changes in this run configuration.

I meant to change installers.cmd

Hi, tried to change and run installers.cmd

Almost at the end of the build, it failed with the following exception:

FATAL: java.lang.RuntimeException: java.lang.RuntimeException: java.nio.file.NoSuchFileException: C:\Jay\codebase_general\JetBrains\221_Final\intellij-community\..\build\plugins-autoup
load.txt

Found the solution from here

Does it work fine now?
