我有一个maven项目，使用“test”-phase以及“integration-test”-phase。在测试阶段，执行JUnit-Tests，在集成测试中有HTMLUnit-tests。我正在使用Jacoco [1] -maven-plugin来测量我的项目的JUnit测试所完成的代码覆盖。在进行集成测试时，我使用maven-embedded-glassfish-plugin启动glassfish服务器并在执行测试之前部署我的应用程序。
可悲但是真的，我必须暂时禁用jacoco，因为它与“集成测试”阶段不一致。
Jacoco的报告目标是/应该在准备包阶段进行，所以我认为它不应该影响集成测试阶段。但是当我启用jacoco：report时，由于内存大小问题，我的集成测试不再运行了。[/ p>
如何停止jacoco：报告影响整合测试阶段？

好的，所以我看到了问题。
类
的方法jjMoveNfa_0在4203 loc时非常长。因此，您的解决方案应该是避免对此类进行检测。
您可以通过告诉jacoco-maven-plugin来排除包含该类的包“com.steadystate”：
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>${jacoco.version}</version>
<configuration>
<excludes>
<exclude>**com.steadystate*</exclude>
</excludes>
...
</plugin>
