Description

Doing a stackdump while "maven-jar-plugin:3.1.0:jar (default-jar)" shows thread spending a lot of time in UnixNativeDispatcher.getgrgid.

This was not visible in java 8 and jar plugin version 2.6.

Our previous build time has been increased from 5min to 3h 30min.

Tested version Java 11 and 3.1.0 of maven-jar-plugin

 

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>${maven.jar.plugin.version}</version>
<configuration>
 <forceCreation>true</forceCreation>
 <archive>
  <index>true</index>
  <manifest>
    <addClasspath>true</addClasspath>
  </manifest>
 </archive>
</configuration>
</plugin>
