如何创建包含依赖项和所提供范围的Maven uber jar [英] How to create maven uber jar which includes dependencies with scope provided

问题描述

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
    <configuration>
         <archive>
            <manifest>           
                <mainClass>com.XXXX.XXXXOfflineApp</mainClass>
            </manifest>
        </archive>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
    </configuration>
  </plugin>
</plugins>

我具有上面的代码段来创建具有依赖项的jar，但是在pom中，我也提供了一些具有范围的依赖项，但是这些都没有包含在uber jar中，所以我无法更改这些依赖项的范围，因为常规jars build不应该包含它们.因为这些是容器提供的.

I have the above code piece to create an jar with dependencies, but in my pom i also have some dependencies with scope provided but these are not included in the uber jar, Well I cannot change the scope of those dependencies because the regular jars build should not include them.Since those are provided by the container.

推荐答案

预定义的 <dependencySet> 和<scope>provided</scope>.

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3 http://maven.apache.org/xsd/assembly-1.1.3.xsd">
  <id>jar-with-dependencies</id>
  <formats>
    <format>jar</format>
  </formats>
  <includeBaseDirectory>false</includeBaseDirectory>
  <dependencySets>
    <dependencySet>
      <outputDirectory>/</outputDirectory>
      <useProjectArtifact>true</useProjectArtifact>
      <unpack>true</unpack>
      <scope>provided</scope>
    </dependencySet>
    <dependencySet>
      <outputDirectory>/</outputDirectory>
      <useProjectArtifact>true</useProjectArtifact>
      <unpack>true</unpack>
      <scope>runtime</scope>
    </dependencySet>
  </dependencySets>
</assembly>

这将包括运行时通常需要的所有依赖项(因此具有compile和runtime的范围)以及所有具有provided范围的依赖项.

This will include all dependencies normally needed at runtime (so having a scope of compile and runtime) and all dependencies having the provided scope.

您可以通过以下方式配置此描述符格式的使用:

You would configure the use of this descriptor format with:

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <version>2.6</version>
  <executions>
    <execution>
      <id>id</id>
      <phase>package</phase>
      <goals>
        <goal>single</goal>
      </goals>
      <configuration>
        <archive>
          <manifest>
            <mainClass>com.XXXX.XXXXOfflineApp</mainClass>
          </manifest>
        </archive>
        <descriptors>
          <descriptor>path/to/assembly.xml</descriptor>
        </descriptors>
      </configuration>
    </execution>
  </executions>
</plugin>

其中path/to/assembly.xml对应于上述描述符格式的路径，相对于POM的位置.

where path/to/assembly.xml corresponds to the path to the above descriptor format, relative to the location of the POM.
