Gradle cannot build effective model because of failure in pom.xml fo

[de-jcup]

Situation

Our build had some errors outputs from Gradle at at mercedes-benz/sechub#1658.
The reason was the usage of spotless which relies on JDT parts for automated eclipse formatting.

Following output was shown multiple times:

Errors occurred while build effective model from /home/runner/.gradle/caches/modules-2/files-2.1/org.eclipse.platform/org.eclipse.core.expressions/3.8.200/eb159f34083b0135459745f934a6ad5eb61b61c/org.eclipse.core.expressions-3.8.200.pom:
	'modelVersion' must be one of [4.0.0] but is '4.0'. in org.eclipse.platform:org.eclipse.core.expressions:3.8.200

Looking at
https://repo1.maven.org/maven2/org/eclipse/platform/org.eclipse.core.expressions/3.8.200/org.eclipse.core.expressions-3.8.200.pom

The pom.xml contains
<modelVersion>4.0</modelVersion>

The older version (3.8.100) https://repo1.maven.org/maven2/org/eclipse/platform/org.eclipse.core.expressions/3.8.100/org.eclipse.core.expressions-3.8.100.pom contains correctly:
<modelVersion>4.0.0</modelVersion>

Wanted

A gradle build shall have not those warnings when there is a gradle/maven dependency to org.eclipse.core.expressions

Suggested solution

• Change the pom model settings (sorry I did not find the part inside the sources) so next releases have 4.0.0 inside
• Maybe change the existing deployed pom.xml at maven central to correct version in pom.xml for org.eclipse.core.expressions-3.8.200 - if possible

Dup of eclipse-platform/eclipse.platform#180?

[merks]

Yes, it's a dup.
