Maven构建具有依赖关系的程序集 [英] Maven build assembly with dependencies

问题描述

我有独立的java应用程序，我想打包为：myapp.jar。并将所有相关的罐子复制到备用文件夹。理想情况下，我想让maven更新META-INF文件，将所有类路径依赖项jars条目添加到其中。

I have standalone java application, which i wanted to package as: myapp.jar. And all dependent jars to be copied to 'alternate folder'. Ideally, i would like to have maven update META-INF file to add all classpath dependencies jars entries into it.

例如，如果我的项目引用了commons.jar，当我使用这个插件来构建程序集时，它会将所有.class文件和包从commons.jar复制到myappjar-with-dependencies.jar。

for example, if my project is referencing commons.jar, and when i use this plugin to build assembly, it copies all .class files and packages from commons.jar into myappjar-with-dependencies.jar.

maven的问题程序集插件将所有依赖项解析为myappjar-with-dependencies.jar。

The problem with maven assembly plugin unjars all dependencies into myappjar-with-dependencies.jar.

<plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
                <archive>
                    <manifest>
                        <mainClass>com.core.App</mainClass>
                    </manifest>
                </archive>
            </configuration>
            <executions>
                <execution>

推荐答案

你可以尝试

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>com.core.App</mainClass>
                        <addClasspath>true</addClasspath>
                        <classpathPrefix>lib/</classpathPrefix>
                    </manifest>
                </archive>
            </configuration>
        </plugin>
        <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <configuration>
                <descriptors>
                    <descriptor>src/assembly/bin.xml</descriptor>
                </descriptors>
            </configuration>
        </plugin>

src / assembly / bin.xml

src/assembly/bin.xml

<assembly
    xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
    <formats>
        <format>dir</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>
    <dependencySets>
        <dependencySet>
            <outputDirectory>/</outputDirectory>
            <unpack>false</unpack>
            <includes>
                <include>${artifact}</include>
            </includes>
        </dependencySet>
        <dependencySet>
            <outputDirectory>/lib</outputDirectory>
            <unpack>false</unpack>
            <excludes>
                <exclude>${artifact}</exclude>
            </excludes>
        </dependencySet>
    </dependencySets>
</assembly>

将其设为

mvn clean package assembly:single
