Maven无法找到执行的主类
问题描述:
尽管代码正在使用“maven clean install”进行编译,并且创建了.jar文件,但在执行它时抱怨“没有主清单属性”,在matrixexplorer-0.0.1中。罐”。我已经添加mainClass标签在我的POM文件,所以我不能明白的问题Maven无法找到执行的主类

答
在构建部分,而不是
<groupId>at.tugraz.iicm</groupId>
<artifactId>matrixexplorer</artifactId>
你需要
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.0.0</version>
您可以解压缩您的jar文件的内容并将Manifest.mf文件内容放入您的问题中吗?为什么它失败的线索应该在那里。 –
