方式一

通过maven-jar-plugin指定outputDirectory输出路径

可以排除某些配置文件，没有文件夹的话会自动创建！

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
        <!-- 指定打包的jar包输出路径 -->
        <outputDirectory>D:\test</outputDirectory>
        <!--不打入jar包的文件类型或者路径 -->
        <excludes>
            <exclude>**/*.properties</exclude>
            <exclude>**/*.xml</exclude>
            <exclude>**/*.yml</exclude>
            <exclude>static/**</exclude>
            <exclude>templates/**</exclude>
        </excludes>
    </configuration>
</plugin>

方式二

通过maven-resources-plugin指定outputDirectory输出路径

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <executions>
        <execution>
            <id>copy-resources</id>
            <phase>package</phase>
            <goals>
                <goal>copy-resources</goal>
            </goals>
            <configuration>
                <encoding>UTF-8</encoding>
                <!--打成jar包后复制到的路径 -->
                <outputDirectory>
                    D:\test1
                </outputDirectory>
                <resources>
                    <resource>
                        <!--项目中的路径 -->
                        <directory>src/main/resources/</directory>
                    </resource>
                </resources>
            </configuration>
        </execution>
        <!--可配置多个提取复制路径只需要 “<id>”名字不一样即可 -->
        <execution>
            <id>copy-bulid</id>
            <phase>package</phase>
            <goals>
                <goal>copy-resources</goal>
            </goals>
            <configuration>
                <encoding>UTF-8</encoding>
                <outputDirectory>
                    D:\test2
                </outputDirectory>
                <resources>
                    <resource>
                        <directory>target</directory>
                    </resource>
                </resources>
            </configuration>
        </execution>
    </executions>
</plugin>

方式三

通过maven-antrun-plugin复制jar包

Maven已经成为Java 工业领域事实上的构建标准，但在某些情况下，如果可以用Ant命令，还是很方便的。

借助 maven-antrun-plugin 插件，可以在Maven执行时，额外执行Ant脚本如下列配置所示：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.8</version>
    <executions>
        <execution>
            <id>install</id>
            <phase>install</phase>
            <configuration>
                <target>
                    <echo message="*******************install*******************" />
                    <mkdir dir="${basedir}/target/classes" />
                    <copy todir="../target/commons" overwrite="true">
                        <fileset dir="${project.build.directory}"
                            erroronmissingdir="false">
                            <include name="*.jar" />
                        </fileset>
                    </copy>
                    <move file="${project.build.directory}/xxxxxxx.jar"
                        tofile="${project.build.directory}/xxx.jar" />
                </target>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
        <execution>
            <id>clean</id>
            <phase>clean</phase>
            <configuration>
                <target>
                    <echo message="*******************clean*******************" />
                    <delete dir="target" />
                    <mkdir dir="${basedir}/target/classes" />
                </target>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
</plugin>

<execution>是可执行命令，可以修改maven的命令执行过程，下面的两个execution是修改了install和clean；

<echo>是打印命令；

<mkdir>是创建文件夹命令；（文件夹里面没有东西时好像不会创建出来）

<copy>是复制命令，其中todir是目标文件夹，overwrite是覆盖旧文件，<fileset dir="xxxx">是源文件，<include>是包含jar包；

<move>是移动文件或者修改名称命令

<delete>是删除命令；

• ${basedir} 指的是 项目根路径 

• ${project.build.directory} 指的是 target所在目录

• ${project.build.finalName} 指的是 jar包前缀名

方式四

通过maven-antrun-plugin嵌入build.xml文件

如下列配置所示：

将build.xml放到项目根路径下，使用<ant antfile="${basedir}/build.xml">嵌入build.xml文件即可。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.8</version>
    <executions>
        <execution>
            <id>install</id>
            <phase>install</phase>
            <configuration>
                <target>
                    <property name="compile_classpath"
                        refid="maven.compile.classpath" />
                    <property name="runtime_classpath"
                        refid="maven.runtime.classpath" />
                    <property name="test_classpath"
                        refid="maven.test.classpath" />
                    <property name="plugin_classpath"
                        refid="maven.plugin.classpath" />
 
                    <ant antfile="${basedir}/build.xml">
                        <target name="test" />
                    </ant>
                </target>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
</plugin>

方式五

使用distributionManagement设置存放路径

这种方式没有通过插件，而是直接配置distributionManagement

使用deploy命令可以部署到目标文件夹，没有文件夹的话会自动创建！

<distributionManagement>
    <repository>
        <id>localRepository</id>
        <url>file:D:/testRepository</url>
    </repository>
</distributionManagement>

扩展：使用maven-dependency-plugin 插件将依赖包导出到指定文件夹

这种方式是将依赖包输出到指定路径

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <id>copy-dependencies</id>
            <phase>package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <!-- 指定输出路径 -->
                <outputDirectory>D:\test2</outputDirectory>
                <excludeTransitive>false</excludeTransitive>
                <stripVersion>false</stripVersion>
                <includeScope>runtime</includeScope>
            </configuration>
        </execution>
    </executions>
</plugin>
