Gradle import of 4.1.1 release cannot be found

[codeanticode]

If a Gradle project includes processing-core:4.1.1 as dependency, the build fails with

ERROR: Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve org.p5android:processing-core:4.1.1.

even though the packages are available on JCenter.

I think I have the same issue using the 4.1.1 core image via Gradle, i.e.

Execution failed for task ':app:checkDebugAarMetadata'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
   > Could not resolve org.p5android:processing-core:4.1.1.
     Required by:
         project :app
      > Could not resolve org.p5android:processing-core:4.1.1.
         > Could not parse POM https://jcenter.bintray.com/org/p5android/processing-core/4.1.1/processing-core-4.1.1.pom
            > Missing required attribute: dependency groupId

while 4.0.4 seems to work without issues.

Completely forgot about this one. I just made a 4.2.0 release on JCentral, @adamreichold could you confirm if it sill affected by the same problem? Thank you!

[adamreichold]

Yes, it is still affected with the same error message.

FAILURE: Build failed with an exception.

I wonder whether the dependency on the Android runtime is not indeed just missing a groupId, i.e.

<dependency>
    <groupId>com.google.android</groupId>
    <artifactId>android</artifactId>
    <scope>runtime</scope>
</dependency>

instead of

<dependency>
    <artifactId>android</artifactId>
    <scope>runtime</scope>
</dependency>

c.f. https://github.com/simpligility/android-maven-plugin/blob/master/src/test/projects/helloflashlight/pom.xml (I also wonder whether the scope should be provided instead of runtime?)

Ok, thanks for confirming. This might also be a good opportunity to update the generation of the maven artifacts using the maven-publishing plugin (#623), so the process is completely automated.

Solved by including the processing-android dep from the self-hosted repo: #623
