自定义生命周期中断Surefire: Maven中的测试

Question

我有一个插件，创建一个特殊的zip文件作为构建过程的一部分。
为此，它定义了一个自定义打包类型'wcc'和一个自定义生命周期。
当我运行mvn package时，应用程序构建我的zip文件很好，一切正常。
(注意:它是跳过单元测试来做到这一点。)

然而，当我运行mvn test时它失败了。

并吐出以下日志:

如果我将<packaging>从wcc更改为jar，那么我的测试运行并通过得很好。

那么为什么我得到这个错误，更重要的是我如何修复它?

---

Maven surefire插件只支持java.lang.String属性。我的插件有一对java.io.File属性。

@Parameter(property = "componentZip", defaultValue = "${componentLocation}")
protected File componentZip;
@Parameter(property = "manifestFile", defaultValue = "${project.basedir}/manifest.hda")
protected File manifestFile;

这些属性被我的插件用来打包zip文件，同时适当地打包文件，并确保它是按照预期的格式构建的。

我怎样才能确保忽略这些配置属性?我需要让他们String和添加转换到File在我的插件，它是这样使用的吗?

Answer 1

我找到我的问题了。我为initialize阶段定义了一个Mojo。它正在处理我的配置并设置默认值。它设置的一个值是componentZip。为了确保它被迁移到后面的阶段，它将它存储在Properties、UserProperties和SystemProperties中。将它和属性更新代码转换为String解决了我的问题。
