# arrow-meta

Is it possible to get a clean, working IntelliJ project setup for arrow-meta?
I'm using 2020.1.2 rc. I've cloned current master of arrow-meta, imported it as a Gradle project, but still get unresolved references. E.g. ExtensionPhase in valueArgumentCoercion.kt and many other files in the idea-plugin module.
I'd be glad to any help here.

Hi @Joachim Ansorg, master branch is a stable branch. Commits merged on master branch need to pass the build check and tests. ExtensionPhase comes from compiler-plugin. Do errors raise when building the idea-plugin module?

[Joachim Ansorg]

gradle is building fine, IntelliJ fails to resolve the class in the editor. I was wondering if anyone knows how to force IntelliJ to do the right thing here

[Rachel]

Invalidate caches and restart works for me in those cases

[Joachim Ansorg]

I just tried that, it didn't work.
But I also tried to go back to 2019.3 and this seems to work. This means that 2020.1 seems to be broken with the Gradle setup of arrow-meta, at least for me 😞
I can work with 2019.3 for now, that's good enough

[Rachel]

Oh no... I'm going to try 2020.1

[Rachel]

@Joachim Ansorg, it doesn't work for me. I realized that Intellij doesn't ask things when opening (importing settings) neither when importing a project, it's opened without asking configuration things. I tried latest release: 2020.1.1 (not rc)

[Rachel]

@Joachim Ansorg, I tried other Gradle projects and they worked properly

[Rachel]

So I came back to Arrow Meta and I realized that the problem is just with idea-plugin and dependencies with compiler-plugin

[Rachel]

However, dependencies between compiler-plugin and meta-test work

[Rachel]

So it seems the problem is the shadowed jar

[Rachel]

It seems the new Intellij doesn't know how to manage the dependency of a shadowed jar

[Joachim Ansorg]

thanks for your thorough analysis of this issue! I agree that this seems like an issue with the shadowed jar. But unfortunately I don't know how to fix this. YouTrack might have some clues, but I doubt it

[Rachel]

I remember now that I got a similar issue when creating an example, however I was using 2019.3 and I didn't understand the reason why I didn't get that issue with Arrow Meta workspace: https://github.com/johnrengelman/shadow/issues/264

[Rachel]

@Joachim Ansorg while we're investigating another way to solve it, you could add this dependency to idea-plugin: compileOnly project(':compiler-plugin') because it doesn't impact on the plugin or library (POM, jar and ZIP from idea-plugin remain the same as before)

[Joachim Ansorg]

thank you @Rachel, I'll try that

[Joachim Ansorg]

@Rachel I've tried it. The IDE is working again with this change. But the idea-plugin module doesn't compile anymore due to compilation errors in a few files

[Rachel]

Thanks @Joachim Ansorg, I didn't get those errors... please, could you share one of them?

[Joachim Ansorg]

@Rachel With gradle clean publishAndRunIde I'm seeing this and bunch of similar errors:

Task :idea-plugin:compileKotlin FAILED
e: /IslandWork/source/arrow-meta/idea-plugin/src/main/kotlin/arrow/meta/ide/IdeMetaPlugin.kt: (15, 6): Class 'IdeMetaPlugin' is not abstract and does not implement abstract base class member public abstract fun registerProjectComponents(project: MockProject, configuration: CompilerConfiguration): Unit defined in arrow.meta.MetaPlugin

[Rachel]

Thanks @Joachim Ansorg, maybe it's caused by the transitive dependencies. I'll review it 👍

Hi @Joachim Ansorg I am working on a few missing peaces to allow feature derivation through 3rd party plugins using Arrow Meta.
Depending, on some on going work in Meta. I hope to address it this weekend.
Means, currently the features build with Meta, are not picked up by IntelliJ.

[Imran/Malic]

It’s not a big concern, but I am drafting an encoding, which allows coherent overrides at the right lifecycle phase.

[Imran/Malic]

Instead of going for a monoidal construction, which forces Meta features in 3rd party plugins.
