Is there a reason why using such an old version of a plugin? search.maven.org/artifact/org.apache.felix/maven-bundle-plugin. Upgrade to most recent version of the plugin. – Electioneer

Answer 1

Based on: https://github.com/FasterXML/oss-parent/issues/27

You need a newer version of the maven bundle plugin.

Try to add this to the plugins section of your POM file:

<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>5.1.1</version>
</plugin>

Answer 2

For me this was caused by using Java 17 by default, while the source repo I tried to build uses Java 11. Setting JAVA_HOME to 11 made Maven work again. E.g. on Linux:

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64

I was able to build the master branch at 2.3.0-SNAPSHOT with JDK 17, but had to downgrade to 11 to build 1.5. – Manutius

Answer 3

Ran into the same issue building RUPS on Windows 10. Using Java SDK 16.0.1, Apache Maven 3.8.1. I used the plugin POM code suggested by Archi for maven-bundle-plugin. But also wound up updating plugin launch4j (also in the POM file) from 1.7.25 to 2.1.1. This successfully created the RUPS jar. (Even a blind squirrel finds a nut once in a while.)
