</project>

从命令提示符处执行了jar：

java -jar TestAssure-1.0.1.jar

Getting Error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/poi/ss/usermodel/Workbook
            at com.test.decimal.rest.Main.main(Main.java:9)

Answer 1

您应该执行胖子jar，其中包括项目的依赖项。

它应该位于target目录下，包括文件名中的jar-with-dependencies。
