["Tim Pizey (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-9140?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15068041#comment-15068041 ] 

Tim Pizey commented on AMBARI-9140:
-----------------------------------

Me too:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.4:site (default-site) on project energy: failed to get report for org.apache.maven.plugins:maven-surefire-report-plugin: Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.19:test (default-test) on project energy: ExecutionException Error occurred in starting fork, check output in log -> [Help 1]

Running under Jenkins. 

Surfire configuration: 
     <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.19</version>
        <configuration>
          <printSummary>true</printSummary>
          <redirectTestOutputToFile>true</redirectTestOutputToFile>
          <parallel>classes</parallel>
          <reuseForks>true</reuseForks>
          <forkCount>1C</forkCount>
          <threadCount>1</threadCount>
        </configuration>
      </plugin>

This started to break when reuse threads was set to true.
