Maven Shade Plugin生产两个罐子

直到现在我使用maven程序集插件为每个工件生成两个JAR - 编译源和依赖项 - 原因很简单 - 仅通过网络部署已编译的源比部署一体式JAR要快得多拥有40 MB的数据。

由于覆盖了内部文件,我不得不切换maven shade插件才能使用<transformers>功能。但是我无法管理两个执行:

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <executions>
      <execution>
        <id>shade-libs</id>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
          <outputFile>target/assembly/${project.artifactId}-libs.jar</outputFile>
          <artifactSet>
            <excludes>
              <exclude>...</exclude>
            </excludes>
          </artifactSet>
          <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
              <resource>META-INF/spring.handlers</resource>
            </transformer>
            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
              <resource>META-INF/spring.schemas</resource>
            </transformer>
          </transformers>
        </configuration>
      </execution>
    </executions>
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <executions>
      <execution>
        <id>shade-main</id>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
          <outputFile>target/assembly/${project.artifactId}.jar</outputFile>
          <artifactSet>
            <includes>
              <include>...</include>
            </includes>
          </artifactSet>
        </configuration>
      </execution>
    </executions>
  </plugin>
</plugins>

当我运行mvn package时,只运行第二次执行。第一个总是被忽略。使用maven程序集插件,它可以很好地工作。

当然解决方案可能是同时使用装配和阴影插件,但我希望找到更一致的解决方案。

不是两次定义插件,只需定义一次但有两个execution部分。所以在你的情况下,它将是:

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <executions>
      <execution>
        <id>shade-libs</id>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
          <outputFile>target/assembly/${project.artifactId}-libs.jar</outputFile>
          <artifactSet>
            <excludes>
              <exclude>...</exclude>
            </excludes>
          </artifactSet>
          <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
              <resource>META-INF/spring.handlers</resource>
            </transformer>
            <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
              <resource>META-INF/spring.schemas</resource>
            </transformer>
          </transformers>
        </configuration>
      </execution>
      <execution>
        <id>shade-main</id>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
        <configuration>
          <outputFile>target/assembly/${project.artifactId}.jar</outputFile>
          <artifactSet>
            <includes>
              <include>...</include>
            </includes>
          </artifactSet>
        </configuration>
      </execution>
    </executions>
  </plugin>
</plugins>
