方式一

通過maven-jar-plugin指定outputDirectory輸出路徑

可以排除某些配置文件，沒有文件夾的話會自動創建！

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

方式二

通過maven-resources-plugin指定outputDirectory輸出路徑

<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包后復制到的路徑 -->
                <outputDirectory>
                    D:\test1
                </outputDirectory>
                <resources>
                    <resource>
                        <!--項目中的路徑 -->
                        <directory>src/main/resources/</directory>
                    </resource>
                </resources>
            </configuration>
        </execution>
        <!--可配置多個提取復制路徑只需要 “<id>”名字不一樣即可 -->
        <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

通過maven-antrun-plugin復制jar包

Maven已經成為Java 工業領域事實上的構建標準，但在某些情況下，如果可以用Ant命令，還是很方便的。

借助 maven-antrun-plugin 插件，可以在Maven執行時，額外執行Ant腳本如下列配置所示：

<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>是可執行命令，可以修改maven的命令執行過程，下面的兩個execution是修改了install和clean；

<echo>是打印命令；

<mkdir>是創建文件夾命令；（文件夾里面沒有東西時好像不會創建出來）

<copy>是復制命令，其中todir是目標文件夾，overwrite是覆蓋舊文件，<fileset dir="xxxx">是源文件，<include>是包含jar包；

<move>是移動文件或者修改名稱命令

<delete>是刪除命令；

• ${basedir} 指的是 項目根路徑 

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

• ${project.build.finalName} 指的是 jar包前綴名

方式四

通過maven-antrun-plugin嵌入build.xml文件

如下列配置所示：

將build.xml放到項目根路徑下，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設置存放路徑

這種方式沒有通過插件，而是直接配置distributionManagement

使用deploy命令可以部署到目標文件夾，沒有文件夾的話會自動創建！

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

擴展：使用maven-dependency-plugin 插件將依賴包導出到指定文件夾

這種方式是將依賴包輸出到指定路徑

<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>
                <!-- 指定輸出路徑 -->
                <outputDirectory>D:\test2</outputDirectory>
                <excludeTransitive>false</excludeTransitive>
                <stripVersion>false</stripVersion>
                <includeScope>runtime</includeScope>
            </configuration>
        </execution>
    </executions>
</plugin>
