apache-el 9.0.108+ POM relocation contains unresolved ${project.version}

[scottfrederick]

Summary

Starting with org.mortbay.jasper:apache-el:9.0.108, the published POM is a <distributionManagement><relocation> to org.mortbay.jasper:mortbay-apache-el whose <version> element is the literal string ${project.version}. The placeholder is not interpolated during the publish step, so it appears verbatim in the deployed POM:

  <distributionManagement>
    <relocation>
      <groupId>org.mortbay.jasper</groupId>
      <artifactId>mortbay-apache-el</artifactId>
      <version>${project.version}</version>
      <message>This artifact has been relocated to org.mortbay.jasper:mortbay-apache-el ...</message>
    </relocation>
  </distributionManagement>

The relocation target artifact org.mortbay.jasper:mortbay-apache-el:9.0.118 itself is published correctly.

Ideally a deployed POM should not contain unresolved Maven property references.

Maven

A minimal Maven build with a dependency on apache-el:9.0.118 resolves successfully and logs:

[WARNING] The artifact org.mortbay.jasper:apache-el:jar:9.0.118 has been relocated
    to org.mortbay.jasper:mortbay-apache-el:jar:9.0.118: This artifact has been relocated ...

Gradle

With newer Gradle versions, the placeholder is resolved against the relocated POM's parent and the build succeeds.

With Gradle <= 8.5, there is a resolution failure.

settings.gradle:

rootProject.name = "jasper-el-repro"

build.gradle:

plugins { id "java" }

repositories { mavenCentral() }

dependencies {
    implementation "org.mortbay.jasper:apache-el:9.0.118"
}

task resolveIt {
    doLast {
        configurations.runtimeClasspath.files.each { println it }
    }
}

gradle/wrapper/gradle-wrapper.properties:

  distributionBase=GRADLE_USER_HOME
  distributionPath=wrapper/dists
  distributionUrl=https\://services.gradle.org/distributions/gradle-8.5-bin.zip
  zipStoreBase=GRADLE_USER_HOME
  zipStorePath=wrapper/dists

Run:

./gradlew --refresh-dependencies resolveIt

Output:

* What went wrong:
Execution failed for task ':resolveIt'.
> Could not resolve all files for configuration ':runtimeClasspath'.
   > Could not find org.mortbay.jasper:mortbay-apache-el:${project.version}.
     Required by:
         project : > org.mortbay.jasper:apache-el:9.0.118

Is the Gradle bug fixed with version > 8.5?
If yes, just upgrade or use Maven 😄
I'm just thinking of removing the old artifactId, as we now have enough releases with the relocation.
