使用Maven,我如何构建一个包含我的项目jar和所有依赖jar的distributable？

Question

我有一个项目(类型'jar')(显然)构建一个jar.但该项目有很多依赖性.我希望Maven构建一个包含我的jar,所有依赖jar和一些脚本(启动应用程序等)的"包"或"程序集"

最好的方法是什么？具体来说,让家属进入大会的最佳方法是什么？

Answer 1

对于单个模块,我将使用类似于以下一个(src/assembly/bin.xml)的程序集:

<assembly>
  <id>bin</id>
  <formats>
    <format>tar.gz</format>
    <format>tar.bz2</format>
    <format>zip</format>
  </formats>
  <dependencySets>
    <dependencySet>
      <unpack>false</unpack>
      <scope>runtime</scope>
      <outputDirectory>lib</outputDirectory>
    </dependencySet>
  </dependencySets>
  <fileSets>
    <fileSet>
      <directory>src/main/command</directory>
      <outputDirectory>bin</outputDirectory>
      <includes>
        <include>*.sh</include>
        <include>*.bat</include>
      </includes>
    </fileSet>
  </fileSets>
</assembly>

要使用此程序集,请将以下配置添加到pom.xml:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
      <descriptors>
        <descriptor>src/assembly/bin.xml</descriptor>
      </descriptors>
    </configuration>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

在此示例中,启动/停止脚本位于src/main/command并且捆绑在一起bin,依赖项被捆绑到其中lib.根据您的需求定制它.

这是我创建一个包含文件夹中所有依赖项的distributable .zip(或.tar.gz/ .tar.bz2)的解决方案lib.它会:

1. jar使用清单创建一个清单,包括lib目录的依赖关系作为类路径和执行时要运行的主类jar.
2. 将所有相关的jar复制到该target/lib目录.
3. 使用主jar和lib目录的所有相关jar创建可分发的`zip.

摘录自pom.xml:

                <mainClass>full.path.to.MainClass</mainClass>

dist.xml:

        </fileSet>
        <fileSet>
            <directory>${project.build.directory}</directory>
            <outputDirectory>/</outputDirectory>
            <includes>
                <include>*.jar</include>
            </includes>
        </fileSet>
        <fileSet>
            <directory>${project.build.directory}/lib</directory>
            <outputDirectory>lib</outputDirectory>
            <includes>
                <include>*.jar</include>
            </includes>
        </fileSet>
        <fileSet>
            <directory>${project.build.directory}/site</directory>
            <outputDirectory>docs</outputDirectory>

这dist.xml是从bin描述符格式派生的:http://maven.apache.org/plugins/maven-assembly-plugin/descriptor-refs.html#bin
