本地扫描maven项目依赖jar的license信息

添加plugin

    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>license-maven-plugin</artifactId>
        <version>2.4.0</version>
        <configuration>
            <!--指定输出内容的模版，方便采集梳理-->
            <fileTemplate>/Users/aaa/your_dir/third-party-file.ftl</fileTemplate>
        </configuration>
        <executions>

在项目根目录执行命令

通过outputDirectory参数，把所有输出文件汇集到一起，通过thirdPartyFilename参数，区分不同module的文件命名

mvn license:add-third-party -Dlicense.outputDirectory=/your_directory -Dlicense.thirdPartyFilename=project-name-'${project.artifactId}'.txt
