Maven相关常用操作——实用指南

• 将jar 打到本地仓库

mvn install:install-file -Dfile=D:\protocol.jar -DgroupId=com.gdc -DartifactId=protocol -Dversion=1.0.0 -Dpackaging=jar -DgeneratePom=true 

• 配置JDK1.8 插件

<plugin>  
    <groupId>org.apache.maven.plugins</groupId>   
    <artifactId>maven-compiler-plugin</artifactId>  
    <configuration>  
        <source>1.8</source>  
        <target>1.8</target>  
        <encoding>UTF-8</encoding>  
    </configuration>  
</plugin>

• 配置JDK1.7 插件

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-compiler-plugin</artifactId>
	<version>3.1</version>
	<configuration>
		<source>1.7</source>
		<target>1.7</target>
                <encoding>UTF-8</encoding>  
	</configuration>
</plugin>

• 打包发布时，跳过单元测试

<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
        <skipTests>true</skipTests>
    </configuration>
</plugin>

• 将代码单独打包成一个jar

    <artifactId>maven-jar-plugin</artifactId>
    <version>3.1.0</version>
    <configuration>
        <!-- 存档 -->
        <archive>
            <manifest>
                <!-- 项目启动类 -->
                <mainClass>com.goldcard.test.openlink.LoadrunnerOpenlinkApplication</mainClass>
                <!-- 依赖的jar的目录前缀 -->
                <classpathPrefix>../lib</classpathPrefix>
                <!-- 使用唯一版本 -->
                <useUniqueVersions>false</useUniqueVersions>
                <!-- 添加classpath 开关 -->
                <addClasspath>true</addClasspath>
                <addDefaultImplementationEntries>true</addDefaultImplementationEntries>
                <addDefaultSpecificationEntries>true</addDefaultSpecificationEntries>
            </manifest>
            <!-- 配置清单（MANIFEST）属性 -->
            <manifestEntries>
                <Class-Path>../resources</Class-Path>
            </manifestEntries>
        </archive>
    </configuration>
</plugin>

• 依赖包打到指定目录插件

<!-- 将依赖包打包到 lib 目录 -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <version>3.1.0</version>
    <executions>
        <execution>
            <phase>prepare-package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <!-- 依赖包存放的位置 -->
                <outputDirectory>target/lib</outputDirectory>
                <overWriteReleases>false</overWriteReleases>
                <overWriteSnapshots>false</overWriteSnapshots>
                <overWriteIfNewer>true</overWriteIfNewer>
                <includeScope>compile</includeScope>
            </configuration>
        </execution>
    </executions>
</plugin>

• 资源文件插件

<!-- 此插件在Maven 多环境切换时，必须添加 -->
<plugin>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.1.0</version>
    <inherited>true</inherited>
    <configuration>
        <encoding>UTF-8</encoding>
        <!-- 配置资源文件中的变量分隔符（标识符），这里配置了两种变量分隔符 -->
        <delimiters>
            <delimiter>${*}</delimiter> <!-- 以${}为分隔符，例如 ${spring.profiles.active}  -->

    </configuration>
    <executions>
        <execution>

                    <transformer  
                        implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">  
                        <!--指定main方法-->
                        <mainClass>com.goldcard.Test</mainClass>
