Excluding package with maven-compiler-plugin works for one package but doesn't work for another
提问by Leem.fin
My project has the following package structure:
我的项目具有以下包结构：
src/
com.my.app.school.course
-Course.java
...
com.my.app.school.course.free
-CourseFree.java
I use Maven to build the project, in my pom.xml, I defined maven-compiler-pluginto test excluding a package with all its java classes.
我使用 Maven 来构建项目，在我的 pom.xml 中，我定义了maven-compiler-plugin来测试排除一个包及其所有 java 类。
I first tried following way to excludepackage com.my.app.school.course.free:
我首先尝试以下方法来排除包com.my.app.school.course.free：
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<excludes>
<exclude>**/com/my/app/school/course/free/*</exclude>
</excludes>
</configuration>
</plugin>
</plugins>
</build>
It works!I mean after run mvn clean install, the final build under target/classes/ doesn't have the package com/my/app/school/course/free.
有用！我的意思是在 run 之后mvn clean install， target/classes/ 下的最终构建没有 package com/my/app/school/course/free。
Then, I tried to exclude package com.my.app.school.course. I simply replacethe above <exclude>tag with value <exclude>**/com/my/app/school/course/*</exclude>. I thought it should work too , but it doesnt! Under target/classes/ I see all packages, no package is excluded. Why?
然后，我尝试排除 package com.my.app.school.course。我只是用 value替换了上面的<exclude>标签<exclude>**/com/my/app/school/course/*</exclude>。我认为它也应该工作，但它没有！在 target/classes/ 我看到所有包，没有包被排除在外。为什么？
What I want to achieve is to exclude package com.my.app.school.coursebut keep pacakge com.my.app.school.course.free, how to achieve this?
我想要实现的是排除 packagecom.my.app.school.course但保留 pacakge com.my.app.school.course.free，如何实现？

I feel it might be because the package I tried to exclude contain java classes that have been used in other packages. I will verify my guess.
我觉得可能是因为我试图排除的包包含在其他包中使用过的 java 类。我会验证我的猜测。

Ok, I found the reason why the exclusion doesn't work.
好的，我找到了排除不起作用的原因。
Because some java classes under the package which I tried to exclude have been used in other packages. Seems maven-compiler-plugin is smart to detect that.
因为我试图排除的包下的一些java类已经在其他包中使用了。似乎 maven-compiler-plugin 很聪明地检测到这一点。
