AssertionFailedError分叉的Java VM因不存在的测试套件而异常退出 [英] AssertionFailedError Forked Java VM exited abnormally for non existing test suite

问题描述

这在SO上可能看起来有些重复，但是我看过此，此和

This may look duplicate to something on SO however I have looked at this, this, this and this but have not found the solution that works.

我遇到的问题是，对于不存在的测试套件，我在jenkins上收到此错误.下面是jenkins ant生成日志中打印的错误；

The problem I have is I am getting this error on jenkins for non existing test suite. Below is the error printed in jenkins ant build log;

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

现在您可以看到它似乎在com.smartstream.control.engine.validation.Batch-With-Multiple-Tests上失败了，但是我在整个工作区中没有任何这样的测试套件.我什至在项目的任何地方都找不到它作为文字字符串.

now as you can see it seems to be failing on com.smartstream.control.engine.validation.Batch-With-Multiple-Tests however I don't have any such test suite in my entire workspace. I couldn't even find it as a literal string anywhere in the project.

工作区中的以下搜索未返回任何内容；

The below search in the workspace returned nothing;

Windows findstr均不显示；

neither did the windows findstr;

我试图增加蚂蚁的构建记忆和permgen都无济于事.该版本使用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；

I have tried increasing the ant build memory and permgen to no avail. The build is running with java 1.7.0_80-b15 and ant 1.9.6. Below is the junit ant task specification in engine/build.xml file;

    <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>

到目前为止我尝试过的事情

• 检查了詹金斯工作的Delete workspace before build starts以获得完整的构建版本.
• 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256m，已更新为512m
• 在蚂蚁任务中使用了fork和showoutput属性
• 从最初的尝试中更新了Java和ant版本

• checked Delete workspace before build starts on jenkins job for a full clean build.
• Initial xmx was 512m I updated it to be 1024m and then later 1536m
• Initial perm size was 256m, have updated to 512m
• have played around with fork and showoutput attributes in ant task
• updated java and ant versions from initial try

任何帮助将不胜感激.

Any help would be greatly appreciated.

推荐答案

我找到了解决此问题的方法.我必须为ant启用详细日志记录，并通过该操作观察到以下堆栈跟踪；

I found a solution to this issue. I had to enable verbose logging for ant and through that the following stacktrace was observed;

Caused by: java.io.IOException: Cannot run program "u:\jenkins\tools\hudson.model.JDK\Java7\jre\bin\java.exe" (in directory "u:\jenkins\workspace\control.unittests.execution.time.test\engine"): CreateProcess error=206, The filename or extension is too long

由于jenkins根据构建作业名称创建工作区，因此太长时间以致无法通过它创建派生的vm.我更改了詹金斯的工作名称，并解决了该问题.

Since jenkins creates workspace based on the build job name it was too long to create forked vm through it. I changed the jenkins job name and it resolved the issue.
