maven java项目打包发布插件 maven-assembly-plugin

1.插件安装在pom.xml中配置

<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4.1</version>
<configuration>
<descriptors> <!--描述文件路径-->                           <descriptor>src/main/assembly/assembly.xml</descriptor>
</descriptors>
</configuration>
<executions>
<execution>
<id>make-tar-gz</id>
<!-- 绑定到package生命周期阶段上 -->
<phase>package</phase>
<goals>
<!-- 绑定到package生命周期阶段上 -->
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>

其中中的内容即为assembly.xml文件的路径

2.assembly文件配置

<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">
<id>distribution</id>
<formats>
<format>tar.gz</format>
</formats>
<includeBaseDirectory>true</includeBaseDirectory>
<fileSets>
<fileSet>
<directory>src/main/resources/${package.environment}</directory>
<outputDirectory>conf</outputDirectory>
</fileSet>
<fileSet>
<directory>src/main/assembly/bin</directory>
<outputDirectory>bin</outputDirectory>
</fileSet>
<fileSet>
<directory>logs</directory>
<outputDirectory>logs</outputDirectory>
</fileSet>
<fileSet>
<directory>dump_files</directory>
<outputDirectory>conf</outputDirectory>
</fileSet>
</fileSets>
<dependencySets>
<dependencySet>
<useProjectArtifact>true</useProjectArtifact>
<outputDirectory>lib</outputDirectory>
<!-- 将scope为runtime的依赖包打包到lib目录下。 -->
<scope>runtime</scope>
</dependencySet>
</dependencySets></assembly>

其中fileSet即为项目目录directory对应最终的输出目录outputDirectory
dependencySet中为运行时依赖包的整理到lib下

3.在配置的时候会遇到一个问题
在pom.xml中配置的指定路径(systemPath)的jar包运行时无法打包到lib下。
解决方案
例如一下systemPath配置

<scope>system</scope>
<systemPath>${project.basedir}/lib/tupuApi_1.1.1.jar</systemPath>

在assembly.xml中配置即可

<fileSet>
<directory>lib</directory>
<outputDirectory>lib</outputDirectory>
</fileSet>


4.线上配置和线下配置区分pom.xml中配置

<profiles>
<profile>
<!-- 本地开发环境 -->
<id>dev</id>
<properties>
<package.environment>dev</package.environment>
</properties>
<!-- <activation>
 <activeByDefault>true</activeByDefault>
 </activation> -->
</profile>
<profile>
<!-- 测试环境 -->
<id>test</id>
<properties>
<package.environment>test</package.environment>
</properties>
</profile>
<profile>
<!-- 生产环境 -->
<id>product</id>
<properties>
<package.environment>product</package.environment>
</properties>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
</profile>
</profiles>
