Shadow Version

6.1.0

Gradle Version

6.7

Expected Behavior

This issue is filed per this comment.

Given a multi-module project, where A depends on B, and where B uses this shadow plugin to bundle some external dependencies (in this case, antlr),

1. A and B can be published to external repos and consumed by other projects in the normal way
2. This multi-module project can be viewed as normal in the IDE (no "unresolved references").

Actual Behavior

It seems that 1 might already be fine, but I have only published to maven-local as a proof of concept so far. The issue I'm having is with 2. I have several "unresolved references" in IDEA that were previously resolvable. These references are to classes that were relocated in B. In the past, I simply built the B jar and included it directly in A (with implementation(files("libs/antlr-$internalAntlrVersion.jar")) and jar.from(zipTree("libs/antlr-$internalAntlrVersion.jar"))), and my IDE had no trouble with this. Now I'm using implementation(project(path = ":antlr", configuration = "shadow")) and several relocated classes are red in the IDE.

My best guess right now is that IDEA doesn't really understand configuration = "shadow", but without that project A depended on the unrelocated jar and compilation from the command line failed.

Gradle Build Script(s)

You can find the code at https://github.com/autonomousapps/dependency-analysis-android-gradle-plugin/tree/pub-antlr. (the pub-antlr branch). The most relevant files are:

1. ./build.gradle.kts
2. antlr/build.gradle.kts
3. buildSrc/src/main/kotlin/plugin-publishing.gradle.kts

Content of Shadow JAR (jar tf <jar file> - post link to GIST if too long)

Additional context

Project A is the root project and publishes a gradle plugin. Project B is a normal Java/Kotlin project that uses antlr to create and publish a custom grammar.

An example of inability to resolve symbols (in com.autonomousapps.tasks.ImportFinderTask):

I tried the old "invalidate caches & restart" trick, but it still can't find these symbols.

Possibly relates to https://youtrack.jetbrains.com/issue/IDEA-163411 and also seems like a reprisal of #264

Was just looking at this again and saw this in changelog.

NEW: Support for Gradle Metadata publication via the shadowRuntimeElements configuration. This is a beta feature the hasn't been tested extensively. Feedback is appreciated.

Could you reply with a quick snippet on how I'd use that configuration?

Ah, this actually works: from(components["java"])
