本文介绍了在jenkins中运行maven / surefire构建时间歇性的NoClassDefFoundError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我们正在Jenkins上构建一个大型的多模块Maven项目，包括运行大量的单元测试。
We are building a large multi module Maven project on Jenkins, including running a large number of unit test.
每运行一次，构建就会在RunListener上的 NoClassDefFoundError 上失败 - 它位于单位jar中。从下面的日志中可以看出 - JUnit包含在类路径中。
Once every few builds the build fails on NoClassDefFoundError on RunListener - which is located in the unit jar. As you can see from the log below - JUnit is included in the classpath.
错误似乎完全随机出现。
The error seems to appear completely at random.

推荐答案
尝试在没有<$ c $的情况下运行maven构建c> -T 4 。
功能仍处于试验阶段，似乎<$ c $中存在已知的线程安全问题c> plexus-utils 2.0.5之前的库 - 你使用的是版本1.5.1。
The parallel builds feature in Maven 3 is still in the experimental stages, and it appears that there are known issues with thread safety in the plexus-utils library prior to version 2.0.5 - you're using version 1.5.1.
编辑：
你的问题是这种依赖：
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit47</artifactId>
<version>${testing.surefire.version}</version>
</dependency>
取决于，这又取决于在，这取决于 plexus-utils-1.5.1 。如上所述，这有已知的线程安全问题，这可能是导致问题的原因。我不确定您使用的 surefire-junit47 库的哪些部分，但是如果切换到 surefire-junit4 是一个选项，然后这应该可以解决你的问题。
surefire-junit47 depends on maven-surefire-common, which in turn depends on maven-artifact, which depends on plexus-utils-1.5.1. As stated above, this has known thread safety issues, which is likely what is causing your problems. I'm not sure what parts of the surefire-junit47 library you're using, but if switching to surefire-junit4 is an option, then that should solve your problem.
在看了一下surefire插件的文档后，看起来你需要 surefire-junit47 运行并行测试的提供程序。我会尝试覆盖 plexus-utils 为版本2.0.5，看看是否有效;否则，您可以将 maven-artifact 版本覆盖到3.0.3或更高版本，看看是否有效。
After looking at the docs for the surefire plugin a little more, it looks like you need the surefire-junit47 provider to run parallel tests. I'd try overriding plexus-utils to be version 2.0.5 and see if that works; otherwise, you can override the maven-artifact version to 3.0.3 or higher and see if that works.
