AssertionFailedError分叉的Java VM异常退出非现有测试套件

Question

这可能看起来与SO上的内容重复，但是我查看了this，this，this和this，但未找到有效的解决方案

我遇到的问题是我在jenkins上为不存在的测试套件收到此错误。下面是jenkins ant build log中打印的错误;

compile-tests-run:
    [junit] Testsuite: com.smartstream.control.engine.validation.Batch-With-Multiple-Tests
    [junit] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0 sec

现在你可以看到com.smartstream.control.engine.validation.Batch-With-Multiple-Tests似乎失败了但是我在整个工作区都没有这样的测试套件。我甚至无法在项目的任何地方找到它作为文字字符串。

工作区中的以下搜索没有返回任何内容;

窗户findstr也没有;

我试过增加ant build内存和permgen无济于事。构建使用java 1.7.0_80-b15和ant 1.9.6运行。下面是engine / build.xml文件中的junit ant任务规范;

    <junit dir="." haltonfailure="false" printsummary="yes" forkmode="once" fork="yes" showoutput="yes" failureproperty="tests.failed">
        <classpath location="${build.testclasses}" />
        <classpath location="${resources.dir}" />
        <classpath location="${common.properties}" />
        <classpath location="${common.libs}" />

        <formatter type="xml" />
        <formatter type="plain" usefile="false" />
        <jvmarg value="-Demma.coverage.out.file=${build.coveragereport}/coverage.emma" />
        <jvmarg value="-Demma.coverage.out.merge=true" />
        <jvmarg value="-Xms512m" />
        <jvmarg value="-Xmx1536m" />
        <jvmarg value="-XX:MaxPermSize=512m" />
        <jvmarg value="-XX:-UseSplitVerifier"/>

        <batchtest todir="${build.report}">
            <fileset dir="${test.dir}">
                <include name="**/*Test.java" />                    
                <exclude name="${excludeTestPattern1}" />
                <exclude name="${excludeTestPattern2}" />
                <exclude name="${excludeTestPattern3}" />
                <exclude name="${excludeTestPattern4}" />
                <exclude name="${excludeTestPattern5}" />
            </fileset>
        </batchtest>
    </junit>

到目前为止我尝试了什么

• 在jenkins作业上检查了Delete workspace before build starts以获得完整的清理版本。
• 初始xmx为512m我将其更新为1024m，然后更新为1536m
• 初始烫发大小为256米，已更新至512米
• 在ant task
中使用了fork和showoutput属性
• 从初始尝试
更新了java和ant版本

非常感谢任何帮助。

我找到了解决这个问题的方法。我必须为ant启用详细日志记录，然后观察到以下stacktrace;

由于jenkins基于构建作业名称创建工作区，因此通过它创建forked vm太长了。我改变了jenkins的工作名称并解决了这个问题。
