Question

尽管代码是使用“maven clean install”进行编译并且创建了.jar文件，但在执行时会抱怨“无主要清单属性，在matrixexplorer-0.0.1.jar中”。我已经在我的pom文件中添加了mainClass标记，所以我无法理解这个问题

这是我的pom文件，

在构建部分中，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>
