使用maven-assembly-plugin打包

一、简介

maven-assembly-plugin 是用来帮助打包使用的插件

maven-assembly-plugin 有:

1. 内置的Assembly DescriptorRefs
2. 自定义Assembly Descriptors

支持的打包类型:

1. zip
2. tar
3. tar.gz (or tgz)
4. tar.bz2 (or tbz2)
5. jar
6. dir
7. war

二、内置的Assembly DescriptorRefs

maven-assembly-plugin 有内置的DescriptorRef

• bin: 类似于默认打包，会将bin目录下的文件打到包中
• jar-with-dependencies: 会将所有依赖都解压到生成的包中
• src: 只将源码目录下的文件打包
• project: 将整个project资源打包

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
    <executions>
        <execution>
            <id>make-assembly</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</plugin>

三、自定义Assembly Descriptors

1.pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.example</groupId>
    <artifactId>package-test</artifactId>
    <version>1.0-SNAPSHOT</version>

    <packaging>jar</packaging>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <commons.version>2.6</commons.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>commons-lang</groupId>
            <artifactId>commons-lang</artifactId>
            <version>${commons.version}</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <descriptors>
                        <!-- 描述文件 -->
                        <descriptor>src/assembly/release.xml</descriptor>
                    </descriptors>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <!-- 绑定到package生命周期 -->
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>

2.描述文件

release.xml

          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">

            <unpack>false</unpack>
        </dependencySet>
    </dependencySets>
