复制资源时完全搜索和替换源文件中的字符串 [英] Full search and replace of strings in source files when copying resources

问题描述

我有一些使用包前缀的Java源文件(它们在模拟某些JDK类).我将这些文件与前缀一起使用以针对某些单元测试运行.如果测试通过，我想生成一个包含源文件但从所有Java文件中删除包前缀的jar.

I have some java source files that use a package prefix (they are emulating some JDK classes). I use these files with the prefix to run against some unit tests. If the tests pass I want to produce a jar that contains the source files but with the package prefix removed from all the java files.

我正在使用Maven进行构建.有人知道这样做的方法吗?本质上，我想要的是类似资源插件过滤功能的东西，但是可以正确搜索和替换(例如:s/my.package.prefix .//g)，而不是对$ {vars}进行过滤.

I am using maven for builds. Does any one know of a way to do this? Essentially what I want is something like the resources plugin filtering feature, but that does proper search and replace (like: s/my.package.prefix.//g), rather than filtering on ${vars}.

推荐答案

这可以通过antrun插件解决.首先，需要使用以下命令将源复制到目标目录:

This can be solved with the antrun plugin. Firstly the sources need to be copied to the target directory, with:

<build>
  ...
  <resources>
    <resource>
      <directory>src/main/java</directory>
      <includes>
        <include>**/*.java</include>
      </includes>
    </resource>
  </resources>
  ...
</build>

其次，您使用antrun插件的replace任务在prepare软件包阶段替换文件

Secondly you use the replace task of the antrun plugin to replace the files using the prepare package phase

<build>
    ...
  <plugin>
    <artifactId>maven-antrun-plugin</artifactId>
    <executions>
      <execution>
        <phase>prepare-package</phase>
        <configuration>
          <tasks>
            <replace token= "my.package.prefix." value="" dir="target/classes">                                 
              <include name="**/*.java"/>
            </replace>
          </tasks>
        </configuration>
        <goals>
          <goal>run</goal>
        </goals>
      </execution>
    </executions>
  </plugin>
  ...
</build>

这将在process-resources阶段将源文件复制到target/classs，在prepare-package阶段中搜索并替换target/classes目录中的文件，最后将它们压缩在package中阶段.

This will copy the source files to target/classes in the process-resources phase, do a search and replace on the files inplace in the target/classes directory in the prepare-package phase and finally they will jarred up in the package phase.
