执行将类路径设置为生成的项目JAR的Maven单元测试

Question

换句话说，现在我的单元测试的类路径设置为:/$projectpath/target/classes/。

相反，我希望将此类路径设置为:/$projectpath/target/myjarfile.jar。

我曾尝试手动添加和删除依赖项类，如下所示：http://maven.apache.org/plugins/maven-surefire-plugin/examples/configuring-classpath.html，但到目前为止还不起作用。

作为测试生命周期阶段的一部分执行的标准单元测试看不到项目JAR，因为test阶段在package阶段之前执行，所以测试是在Maven生成JAR之前运行的。有关生命周期阶段及其顺序的列表，请参见此页。

您希望它将测试作为集成测试运行，集成测试在integration-test阶段执行。

有许多关于设置Maven以运行集成测试的教程。这里和这里有两个开始。failsafe插件通常用于执行集成测试。
