java – 如何:Eclipse Maven安装具有依赖关系的构建jar

我在Eclipse中使用Eclipse Maven(m2e),我正在运行我的项目,如下所示:

我的pom.xml如下所示:

在我运行maven安装它正在工作…

Maven运行配置:

问题是我生成的.jar它没有包含依赖关系….
我如何配置pom.xml以包含所有我的依赖关系.jar格式,而不是解压缩..因为看起来解压缩是不正确的…

为了确保包括所有的jar可以..我下载并将每个库添加到jar的/ lib文件夹,并且jar正在运行…所以..我唯一的问题是:如何配置pom.xml为了添加所有我的jar格式的依赖

我尝试了所有的方法:

>装配:装配
>装配:单
> assembly:单个我的描述符(一个assemble.xml文件),但它不工作
> maven复制依赖插件,但仍然不能使用Eclipse Maven – m2e

我没有解决方案…任何人都可以告诉我一个适当的方式来添加我的依赖项在jar中?我不敢相信这个maven太复杂了,我找不到我的问题的答案.

先谢谢你

最佳答案
有几种方法来做到这一点.

1)如果您需要一个uber-jar(重新打包所有依赖项),请查看使用和配置maven-shade-plugin

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>1.6</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>shade</goal>
            </goals>
            <configuration>
              <transformers>
                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                  <mainClass>com.group.id.Launcher1</mainClass>
                </transformer>
              </transformers>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

这将解压缩所有依赖关系并将它们合并到一个JAR文件中.

2)如果要将捆绑包中的未打包的JAR文件(可能在lib /下)提供捆绑(zip,tar.gz等),则需要查看maven-assembly-plugin

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>2.3</version>
        <executions>
          <execution>
            <id>create-distro</id>
            <phase>package</phase>
            <goals>
              <goal>single</goal>
            </goals>
            <configuration>
              <descriptors>
                <descriptor>src/main/assembly/dist.xml</descriptor>
              </descriptors>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

请注意,这需要一个汇编描述符src / main / assembly / dist.xml,示例如下所示:

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0">
  <id>distribution</id>
  <formats>
    <format>zip</format>
  </formats>

  <dependencySets>
    <dependencySet>
      <useProjectArtifact>false</useProjectArtifact>
      <useTransitiveDependencies>false</useTransitiveDependencies>
      <unpack>false</unpack>
      <scope>runtime</scope>
      <fileMode>0755</fileMode>
      <directoryMode>0755</directoryMode>
      <outputDirectory>bin</outputDirectory>

      <includes>
        <include>com.group.id:project-launch1</include>
        <include>com.group.id:project-launch2</include>
      </includes>

    </dependencySet>
    <dependencySet>
      <useProjectArtifact>false</useProjectArtifact>
      <useTransitiveDependencies>true</useTransitiveDependencies>
      <unpack>false</unpack>
      <scope>runtime</scope>
      <fileMode>0644</fileMode>
      <directoryMode>0755</directoryMode>
      <outputDirectory>lib</outputDirectory>

      <includes>
        <include>com.group.id:project-lib1</include>
        <include>com.group.id:project-lib2</include>
        <include>com.group.id:project-lib3</include>
        <include>com.group.id:project-lib4</include>
      </includes>

    </dependencySet>
  </dependencySets>
</assembly>

而且由于您正在组装依赖关系,您可以更好地定义pom.xml中的依赖关系,如下所示:

  <dependencies>
    <dependency>
      <groupId>com.group.id</groupId>
      <artifactId>project-launch1</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <type>jar</type>
    </dependency>
    <dependency>
      <groupId>com.group.id</groupId>
      <artifactId>project-launch2</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <type>jar</type>
    </dependency>
    <dependency>
      <groupId>com.group.id</groupId>
      <artifactId>project-lib1</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <type>jar</type>
    </dependency>
    ... and so on ...
  </dependencies>

3)如果您使用可执行JAR文件启动器发送捆绑包,则除了maven-assembly-plugin外,您还可能需要添加一个maven-jar-plugin配置:

  <dependencies>
    <dependency>
      <groupId>com.group.id</groupId>
      <artifactId>project-lib1</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <type>jar</type>
    </dependency>
    <dependency>
      <groupId>com.group.id</groupId>
      <artifactId>project-lib2</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <type>jar</type>
    </dependency>
    <dependency>
      <groupId>com.group.id</groupId>
      <artifactId>project-lib3</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <type>jar</type>
    </dependency>
    ... and so on ...
  </dependencies>

  <build>
    <plugins>
      <plugin>
        <artifactId>maven-jar-plugin</artifactId>
        <configuration>
          <archive>
            <addMavenDescriptor>false</addMavenDescriptor>
            <compress>true</compress>
            <manifest>
              <mainClass>com.group.id.Launcher1</mainClass>
              <addClasspath>true</addClasspath>
              <classpathPrefix>../lib/</classpathPrefix>
            </manifest>
          </archive>
        </configuration>
      </plugin>
    </plugins>
  </build>

请注意,“addClasspath”指令将项目依赖关系添加到类路径.这是JAR启动器所必需的,因为它们明确忽略所有CLASSPATH环境变量.
