仅编译Maven中的选定文件 [英] Compiling only selected files in Maven

问题描述

我想只编译源目录中的选定文件或目录（包括子目录）。我很确定我可以使用< includes> 的 maven-compiler-plugin 的配置来做到这一点，但是它似乎无法正常工作，因为它仍然将所有类编译成 target / classes 。真正奇怪的是，Maven输出表明该设置实际上是有效的，因为：

I want to compile only selected files or directories (including subdirectories) within source directory. I was pretty sure I can do this using <includes> of maven-compiler-plugin's configuration, but it seems to not work as I expect since it still compiles all classes into target/classes. What is really strange, Maven output suggest that the setting actually does its work, because with:

  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.5.1</version>
    <configuration>
      <includes>
        <include>com/example/dao/bean/*.java</include>
      </includes>
    </configuration>
  </plugin>

我有：

[INFO] Compiling 1 source file to c:\Projects\test\target\classes

但没有编译器的配置我有：

but with no compiler's configuration I have:

[INFO] Compiling 14 source file to c:\Projects\test\target\classes

然而，在这两种情况下，所有14个类都被编译我提到的目标/类。你能解释一下还是建议另一个只编译选定文件的解决方案吗？

In both cases however, all 14 classes are compiled into target/classes as I mentioned. Can you explain that or suggest another solution to compile only selected files?

推荐答案

3个类的简单应用程序。

Simple app with 3 classes.

com/company/Obj1.java
com/company/Obj2.java
com/company/inner/Obj3.java  

build in pom.xml

<build>
         <plugins>
            <plugin>
               <groupId>org.apache.maven.plugins</groupId>
               <artifactId>maven-compiler-plugin</artifactId>
               <version>2.0.2</version>
               <configuration>
                  <source>1.6</source>
                  <target>1.6</target>
                  <includes>
                     <include>com/company/inner/*.java</include>
                  </includes>
               </configuration>
            </plugin>
          </plugins>

   </build>  

结果：编译了1个类。

并且包含的​​任何组合都在工作好吧？
或者你的意思是别的什么？

result: 1 class is compiled.
And any combination of includes is working well
or you mean something else?
