AssertionFailedError Forked Java 虚拟机因不存在的测试套件异常退出

Question

这可能看起来与 SO 上的某些内容重复，但是我查看了 this, this, this and this 但没有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。以下是 jenkins ant 构建日志中打印的错误；

compile-tests-run:
    [junit] Testsuite: com.smartstream.control.engine.validation.Batch-With-Multiple-Tests

现在如您所见，它似乎在 com.smartstream.control.engine.validation.Batch-With-Multiple-Tests 上失败了，但是我的整个工作区中没有任何此类测试套件。我什至在项目的任何地方都找不到它作为文字字符串。

在工作区中的以下搜索未返回任何结果；

windows findstr 也没有；

我试过增加 ant 构建内存和 permgen，但没有用。构建是运行 java 1.7.0_80-b15 和 ant 1.9.6。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

检查 Delete workspace before build starts jenkins 作业以获得完全干净的构建。
初始xmx是512m我更新为1024m后来1536m
初始烫发大小为 256m，已更新为 512m
在 ant 任务中玩过 fork 和 showoutput 属性
更新了 java 和最初尝试的 ant 版本

如有任何帮助，我们将不胜感激。

我找到了这个问题的解决方案。我必须为 ant 启用详细日志记录，并通过它观察到以下堆栈跟踪；

由于 jenkins 根据构建作业名称创建工作区，因此通过它创建分叉 vm 太长了。我更改了詹金斯的工作名称并解决了这个问题。
