maven - 如何在 jacoco :report? 之后禁用 jacoco-agent

Question

我有一个 maven 项目，使用“测试”阶段和“集成测试”阶段。在测试阶段，执行 JUnit 测试，在集成测试中有 HTMLUnit 测试。我正在使用 Jacoco[1]-maven-plugin 来测量我的项目的 JUnit 测试完成的代码覆盖率。在进行集成测试时，我使用 maven-embedded-glassfish-plugin 来启动 glassfish-server 并在执行测试之前部署我的应用程序。

可悲但真实，我必须暂时禁用 jacoco，因为它与“集成测试”阶段不协调。

Jacoco 的报告目标是/应该在准备包阶段执行，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[2]，我的集成测试不再运行。

如何阻止 jacoco:report 影响集成测试阶段？

好的，所以我看到了问题。

类的方法 jjMoveNfa_0

http://grepcode.com/file/repo1.maven.org/maven2/net.sourceforge.cssparser/cssparser/0.9.5/com/steadystate/css/parser/SACParserCSS21TokenManager.java

4203 loc 太长了。因此，您的解决方案应该是避免在此类上使用仪器。

您可以通过告诉 jacoco-maven-plugin 这样做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>
