Description

Doing a stackdump while "maven-source-plugin:3.0.0:jar-no-fork (attach-sources)" shows thread spending a lot of time in UnixNativeDispatcher.getgrgid.

This was not visible in java 8 and source plugin version 2.4.

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

Tested version Java 11 and 3.0.0 of maven-source-plugin

maven config:

 <plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-source-plugin</artifactId>
 <version>3.0.0</version>
 <executions>
   <execution>
     <id>attach-sources</id>
     <goals>
       <goal>jar-no-fork</goal>
     </goals>
   </execution>
 </executions>
 </plugin>
