此时IDEA右侧出现ant打包步骤，我们双击release开始打包吧！

打包成功

若出现(请使用 -source 7 或更高版本)等错误，需要在build.xml加入你的source和target版本（JDK版本） 

<!-- Build all Java code. --><target name="compile" description="Compile the source." ><uncommons:compile module="reportng" source="1.8" target="1.8" /></target>

这是因为reportNG通过antlib外部lib文件 uncommons-antlib-0.3.2.jar进行依赖，使用Ant build进行release的，查看uncommons-antlib文件，打开其中antlib.xml，我们可以发现其编译指定默认的jdk版本为1.5，所以如果出现版本问题，请如上修改。 

至此，我们可以去reportng-master\release取我们的jar包了，最终失败截图效果如下
