Question

我有一个Maven项目，我试图打包，但我注意到我所有的Java测试类（但没有我的Scala测试类）和生成的Avro测试类最终都在广口瓶中。

文件夹结构看起来很好：

我还注意到，如果我将junit作为<scope>test</scope>的依赖项添加，我的测试将无法编译，因为它无法找到junit类，所以看起来Maven正在处理我的所有代码包括测试作为main的一部分。

Answer 1

想出来。

问题在于avro-maven-plugin。

它的配置有sourceDirectory和outputDirectory，两者都有测试源路径。

<configuration>
  <sourceDirectory>${project.basedir}/src/test/resources/</sourceDirectory>
  <outputDirectory>${project.basedir}/src/test/java</outputDirectory>
</configuration>

显然这些都干扰了编译器插件，它认为这些目录是主要的源目录，并将它们与其他主类一起编译。这也解释了为什么我的测试在junit依赖被赋予测试范围时无法编译。

解决方案是使用testSourceDirectory和testOutputDirectory代替：

<configuration>
  <testSourceDirectory>${project.basedir}/src/test/resources/</testSourceDirectory>
  <testOutputDirectory>${project.basedir}/src/test/java</testOutputDirectory>
</configuration>

Answer 2

mvn clean install -Dmaven.test.skip = true -X

为什么我的Maven项目打包测试文件？
