maven 不重新打包依赖项

我使用 Maven 程序集插件将所有依赖项收集到一个 jar 文件中。我怎样才能告诉maven不要重新打包依赖项并将它们作为jar文件包含到生成的jar中？

目前我使用以下插件配置。

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

想要的 jar 文件结构：

my-jar-with-dependencies.jar
|-dependency1.jar
|-|-class1.class
|-dependency2.jar
|-|-class2.class
|-...........

而不是

my-jar-with-dependencies.jar
|-class1.class
|-class2.class
|-.............

原文

I use maven assembly plugin to collect all dependencies into one jar file. How can I tell maven not to repack dependencies and include them as jar files into resulting jar?

Currently I use following plugin configuration.

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

wanted structure of jar file:

my-jar-with-dependencies.jar
|-dependency1.jar
|-|-class1.class
|-dependency2.jar
|-|-class2.class
|-...........

and not

my-jar-with-dependencies.jar
|-class1.class
|-class2.class
|-.............

如果我正确理解了这个问题，您想要指定何时应该运行程序集插件。在这种情况下，您应该考虑创建一个构建配置文件并将程序集插件配置添加到新配置文件中。

在 pom.xml 中添加：

<project>
...
 <profiles>
    <profile>
        <id>myprofile</id>
        <build>
            <plugins>
                <plugin>
                    <artifactId>maven-assembly-plugin</artifactId>
                    <executions>
                        <execution>
                            <phase>package</phase>
                            <goals>
                                <goal>single</goal>
                            </goals>
                        </execution>
                    </executions>
                    <configuration>
                        <archive>
                            <manifest>
                                <mainClass>package.Program</mainClass>
                            </manifest>
                        </archive>
                        <descriptorRefs>
                            <descriptorRef>jar-with-dependencies</descriptorRef>
                        </descriptorRefs>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </profile>
 </profiles>
...
</project>

当您希望 maven 运行程序集插件时，您可以使用 -P 开关切换到“mvn”脚本，如下所示：

mvn -Pmyprofile clean package

If I understand the question correctly you want to specify when the assembly plugn should be run or not. I this is the case you should consider creating a build profile and add the assembly plugin configuration to the new profile.

In pom.xml add:

<project>
...
 <profiles>
    <profile>
        <id>myprofile</id>
        <build>
            <plugins>
                <plugin>
                    <artifactId>maven-assembly-plugin</artifactId>
                    <executions>
                        <execution>
                            <phase>package</phase>
                            <goals>
                                <goal>single</goal>
                            </goals>
                        </execution>
                    </executions>
                    <configuration>
                        <archive>
                            <manifest>
                                <mainClass>package.Program</mainClass>
                            </manifest>
                        </archive>
                        <descriptorRefs>
                            <descriptorRef>jar-with-dependencies</descriptorRef>
                        </descriptorRefs>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </profile>
 </profiles>
...
</project>

When you want maven to run the assembly plugin you can then use the -P switch to the 'mvn' script like this:
