maven pom 引入本地jar包

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>
