      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>
