从Maven插件访问项目类 [英] Access project classes from a maven plugin

问题描述

我正在制作一个在测试阶段运行的Maven插件，在使用我的插件的项目的pom.xml配置中，我设置了一个类规范名称，我想使用该类规范名称从我的插件中运行该类，基本上，我正在通过插件从项目内部动态加载类.

I'm making a maven plugin that run in test phase, in pom.xml configuration of a project that uses my plugin, I'm setting a class canonical name that I want to use to run that class from my plugin, basically I'm making a way to have a dynamic class loading of classes inside the project from my plugin.

Class clazz = Class.forName("... class from pom.xml ...")

当我运行它时，会收到预期的"ClassNotFoundException"，似乎类加载器不相同或未共享.

When I run it I receive the expectable "ClassNotFoundException", seems the class loader are not the same or not shared.

有办法做到吗?像是从项目中捕获类加载器，还是通过将依赖项注入到我的插件中来接收它?最好的方法是什么?

There is a way to do it? Like capture the class loader from the project or receive it by dependency injection into my plugin? What is the best way?

推荐答案

我们可以在mojo中使用Hibernate实现，作为实现它的参考:

We can use the Hibernate implementation in mojo can be used as a reference to make it:

在此处签出源代码:

要捕获项目"对象，我们可以使用mojo依赖项注入:

To capture the "project" object, we can use the mojo dependency injection:

/**
 * Dependency injected
 */
 @Parameter(defaultValue = "${project}")
 public MavenProject project;

并使用它在项目类加载器中加载某些类:

And use it to load some class in project class loader:

getClassLoader(this.project).loadClass("com.somepackage.SomeClass")
