某些文件的maven-assembly-plugin

Question

我有多模块项目，这是父pom。

在atoms persitence项目中，我有以下文件：

Com.Atoms.vo。*

Com.Atoms.service。*

Com.Atoms.da.*

在原子-雷格拉斯中我有：

Com.Atoms.ruls.*

如何使用程序集插件创建只包含以下类的jar：

com.atoms.vo.*和com.Atoms.ruls.*？

Answer 1

试着这样做：

<assembly>
    <id>atoms</id>
    <formats>
        <format>jar</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>
    <fileSets>
        <fileSet>
            <directory>${basedir}/target/classes
            </directory>
            <outputDirectory>/</outputDirectory>
            <includes>
                <include>com/atoms/vo.**</include>
                <include>com/atoms/rules/**</include>
            </includes>
        </fileSet>
    </fileSets>
</assembly>

Answer 2

首先，显式指定您希望在pom.xml中使用大于或等于2.2-beta-3的maven程序集插件版本(稍后需要的unpackOptions元素的includes/excludes在2.2-beta-3之前的版本中的行为与预期不同)。我在这里使用2.2-beta-4版本：

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <version>2.2-beta-4</version>
  <configuration>
    <descriptors>
      <descriptor>assemble.xml</descriptor>
    </descriptors>
  </configuration>
</plugin>

然后，使用您选择的模块声明一个moduleSets，并指定要在assembly.xml中使用includes解压它们的二进制内容

<assembly>
  <id>my-assembly</id>
  <formats>
    <format>jar</format>
  </formats>
  <includeBaseDirectory>false</includeBaseDirectory>
  <moduleSets>
    <moduleSet>
      <includes>
        <include>com.atoms:atoms-persistence</include>
        <include>com.atoms:atoms-reglas</include>
      </includes>
      <binaries>
        <outputDirectory>/</outputDirectory>
        <unpack>true</unpack>
        <unpackOptions>
          <includes>
            <include>com/atoms/vo/**</include>
            <include>com/atoms/rules/**</include>
          </includes>
        </unpackOptions>
      </binaries>
    </moduleSet>
  </moduleSets>
</assembly>

最后，从父项目运行以下命令：

mvn clean package assembly:assembly

这将构建一个只包含所需类的target/atoms-parent-1.0-my-assembly.jar。
