maven pom 引入本地jar包

  1. 在pom.xml同级目录下新建lib文件夹，并放入本地jar包。
  2. 配置Jar包的dependency，包括groupId，artifactId，version三个属性，同时还要包含scope和systemPath属性，分别指定Jar包来源于本地文件，和本地文件的所在路径。示例：
<dependency>

    <groupId>cpdetector</groupId>

    <artifactId>cpdetector</artifactId>

    <version>1.0.10</version>

    <scope>system</scope>

    <systemPath>${basedir}/lib/xxx1.0.10.jar</systemPath>

</dependency>

${basedir}是指项目根路径。

3.配置插件将本地jar包打入运行jar/war包中，由于scope=system,默认并不会将Jar包打进jar/war包中，所有需要通过插件进行打包。

   <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId>

                <configuration>

                    <includeSystemScope>true</includeSystemScope>

                </configuration>

            </plugin>

<plugin>

    <groupId>org.apache.maven.plugins</groupId>

    <artifactId>maven-dependency-plugin</artifactId>

    <version>2.10</version>

    <executions>

        <execution>

            <id>copy-dependencies</id>

            <phase>compile</phase>

            <goals>

                <goal>copy-dependencies</goal>

            </goals>

            <configuration>

                <outputDirectory>${project.build.directory}/${project.build.finalName}/WEB-INF/lib</outputDirectory>

                <includeScope>system</includeScope>

            </configuration>

        </execution>

    </executions>

</plugin>

4、将依赖jar包打包至jar包中

方法一：

<build>

        <finalName>包名</finalName>

        <plugins>

            <!--源码编译-->

            <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-compiler-plugin</artifactId>

                <version>3.7.0</version>

                <configuration>

                    <source>1.8</source>

                    <target>1.8</target>

                </configuration>

            </plugin>

            <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-assembly-plugin</artifactId>

                <version>2.4.1</version>

                <configuration>

                    <appendAssemblyId>false</appendAssemblyId>

                    <descriptorRefs>

                        <descriptorRef>jar-with-dependencies</descriptorRef>

                    </descriptorRefs>

                    <archive>

                        <manifest>

                            <mainClass>包程序主类</mainClass>

                        </manifest>

                    </archive>

                </configuration>

                <executions>

                    <execution>

                        <id>make-assembly</id>

                        <phase>package</phase>

                        <goals>

                            <goal>assembly</goal>

                        </goals>

                    </execution>

                </executions>

            </plugin>

        </plugins>

    </build>

方法二：生成含依赖xxx.jar包和original-xxx.jar不含依赖jar包。

 <build>

        <finalName>包名</finalName>

        <plugins>

            <!--源码编译-->

            <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-compiler-plugin</artifactId>

                <version>3.7.0</version>

                <configuration>

                    <source>1.8</source>

                    <target>1.8</target>

                </configuration>

            </plugin>

            <!-- shade插件打包成jar包 -->

            <plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-shade-plugin</artifactId>

                <version>3.1.1</version>

                <executions>

                    <execution>

                        <phase>package</phase>

                        <goals>

                            <goal>shade</goal>

                        </goals>

                        <configuration>

                            <transformers>

                                <transformer

                                        implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">

                                    <mainClass>包程序主类</mainClass>

                                </transformer>

                            </transformers>

                        </configuration>

                    </execution>

                </executions>

            </plugin>

        </plugins>

    </build>
