从单个 Maven 项目创建多个可运行的 Jars(包括依赖项) [英] Create multiple runnable Jars (with dependencies included) from a single Maven project

问题描述

我有一个包含多个主要类的 Maven 项目.我想从这些项目中生成可运行的 Jars(包括所有依赖项).我目前有以下构建配置(使用 maven.assembly):

I have a single maven project that has multiple main classes. I want to generate runnable Jars (that include all dependencies) out of these project. I currently have the following build configuration (using maven.assembly):

<build>
<plugins>
    <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <configuration>
            <archive>
                <manifest>
                    <mainClass>classpath.to.my.mainClass</mainClass>
                </manifest>
            </archive>
            <descriptorRefs>
                <descriptorRef>jar-with-dependencies</descriptorRef>
            </descriptorRefs>
        </configuration>
    </plugin>
</plugins>
</build>

他们是通过 maven-assembly 实现这一目标的方法吗?如果不是，那么实现目标的最简单方法是什么?

Is their a way to achive this with maven-assembly? If not, what is the simplest way to achive my goal?

推荐答案

我无法用 maven-assembly-plugin 以令人满意的方式解决这个问题，所以我去找了一个不同的解决方案.我使用了 onejar-maven-plugin:

I wasn't able to solve this problem with the maven-assembly-plugin in a satisfying way, so I went for a different solution. I used the onejar-maven-plugin:

<build>
  <plugins>
  <plugin>
    <groupId>org.dstovall</groupId>
    <artifactId>onejar-maven-plugin</artifactId>
    <version>1.4.4</version>
    <executions>
      <execution>
        <id>build-first</id>
          <configuration>
            <mainClass>classpath.to.first.Main</mainClass>
            <attachToBuild>true</attachToBuild>
            <classifier>onejar</classifier>
            <filename>first-runnable.jar</filename>
          </configuration>
          <goals>
            <goal>one-jar</goal>
          </goals>
        </execution>
      <execution>
        <id>build-second</id>
          <configuration>
            <mainClass>classpath.to.second.Main</mainClass>
            <attachToBuild>true</attachToBuild>
            <classifier>onejar</classifier>
            <filename>second-runnable.jar</filename>
          </configuration>
          <goals>
            <goal>one-jar</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>
