[Patch] Revise IntelliJ related compiling guide

[gaben]

I tried IntelliJ get it to work following the steps on the wiki page, but some dependencies were missing and couldn't set up the IDE correctly. Ant helped me to build and run, but that's all. Using built-in running/testing/debugging config would be better.

The wiki is maintained by the community, can you please update it? I have no idea what's missing, I'm using Eclipse.

Now I only get 6 errors instead of 100. Currently the only file that fails is scripts\I18nSimilarStrings.java, because can't import
org.openstreetmap.josm.gui.MainApplicationTest and
org.openstreetmap.josm.plugins.PluginHandlerTestIT

Any idea? If I could set up the IDE, I can make the wiki update, probably next month.

[anonymous]

Oh, and I used the github mirror for getting the source.

NB: Another good reason to move to Gradle eventually (#8269), IDE auto config, ​https://www.jetbrains.com/help/idea/gradle.html

I originally wrote this guide. I marked scripts/ as test root:

Thanks, simon04. Although I already tried Gradle, somehow it didn't work. I'll have a second look.

Finally, I can build the source with IntelliJ built-in tools. Now I have another problem. If I want to run JOSM, it fails because can't load the config files:

The working directory is the root folder, I don't know why doesn't recognise the files :/

Ant run config works fine. Gradle doesn't yet.

Gradle cannot import org.openstreetmap.josm.RevisionTask.

This is what I tried:

• Check out JOSM SVN
• File → new → Project from existing source → Select JOSM SVN Directory
• Sources
  • …/josm-svn/scripts com.intellij.ide.util.projectWizard.importSources.JavaModuleSourceRoot@62f77166
  • …/josm-svn/src com.intellij.ide.util.projectWizard.importSources.JavaModuleSourceRoot@19d658b2
  • …/josm-svn/test/functional com.intellij.ide.util.projectWizard.importSources.JavaModuleSourceRoot@32e00861
  • …/josm-svn/test/performance com.intellij.ide.util.projectWizard.importSources.JavaModuleSourceRoot@4068c6fd
  • …/josm-svn/test/unit com.intellij.ide.util.projectWizard.importSources.JavaModuleSourceRoot@5cfb463a
  • …/josm-svn/tools/checkstyle/src com.intellij.ide.util.projectWizard.importSources.JavaModuleSourceRoot@59f7b7e2
• Libraries
  • Deselect all test/data/…
  • Deselect dist
  • (those are probably still too many, but it won't hurt. Just make sure to compile with ANT before committing, so that you know if you used a wrong one in your code)
• Modules as suggested
• Select 1.8 JDK
• Deselect OSGi extension (we don't need it)

Then:

• Mark all dirs with generated code as excluded
• Mark resource directory 'data' for the main module
• styles / images / data are resources with the respective relative output path set.
• Exclude all SVN externals that are copied into the source dir and that do not really belong to JOSM (I don't know why they are even copied exactly there if they are exluded in the build any way)
• Make parsergen directory generated sources
• Add build.xml to ANT files
• Run ant task create-revision-eclipse before run
• Run ant task javacc before compilation
• Run ant task compile-cots before compilation
• Run ant task epsg before run
• Add junit maven dependency
• Fix many other dependecy stuff according to build.xml
• Create run configuration for JOSM

Important note: Since JOSM ant build does not differentiate between different modules and just puts all files in one big directory (which is currently the main reason we have with IDE integration and gradle setup), you should not run josm using ant (since this will pollute the build directory with compiled JOSM and not only CTOS classes and that would cause classes to be on the classpath twice)

Extract this in the josm directory, then open with intellij. Working as of 2019-06-02, will fail as soon as someone changes a library version / …

I'm the OP. Thanks, I'll look at in the near future.
Based on what you wrote and my experiences, it seems much easier to give everyone the project files instead of the steps to setup manually. And just for the case the given config fails, give step by step setup guide as a fallback.

Just registered, I'm the reporter.

Didn't forget, but haven't had the time to deal with the issue. It's on my queue.

[hiddewie]

I am currently adding screenshots and many step-by-step items for getting started with IntelliJ and Ant.

JOSM tree structure change may affect the guide, see #18845.

[simon04]

Here is an updated guide including the changes from #18845 and #16860 – ​https://gist.github.com/simon04/08836edea15864e4b1010f960451369a

[Klumbumbus]

Can you delete all the outdated information on wiki:/DevelopersGuide/CompilingUsingIntelliJ?

[simon04]

Strictly speaking the old content is not outdated, but describes a different approach that is a bit less integrated since it relies less on IntelliJ and more on Ant tasks.

Maybe we can/should keep both?

[Klumbumbus]

OK

[gaben]

The tutorial is already outdated unfortunately because of Ivy, and IntelliJ changed in 2020.1 release. Now by default, it doesn't have the config steps seen in the JOSM tutorial. It's still here, but hidden, see ​https://www.jetbrains.com/help/idea/2020.1/import-project-or-module-wizard.html

Who is not familiar with IntelliJ long enough will not know these options anytime existed. I opt for Simon's gist and deleting the old ones found here in the wiki.

[hiddewie]

Using the current guide without the Ivy integration/plugin within IntelliJ will not allow running tests and compiling test code from the IDE. This makes using an IDE half-useless.

Deleting all the old documentation and replacing it with the content in the gist seems like a good idea. The IdeaIvy plugin works well.
