Can't run .jar because "no main manifest attribute"
提问by NateH06
I've never built an executable .jar before, and I'm trying to do so with a Maven project with IntelliJ, and I can't seem to run the program. I've done it through the Project Structure -> artifacts route, and I've set the main class and locations properly or so I thought, in the configuration:
我以前从未构建过可执行文件 .jar，我正在尝试使用 IntelliJ 使用 Maven 项目来构建，但我似乎无法运行该程序。我已经通过 Project Structure -> artifacts 路线完成了它，并且我已经在配置中正确设置了主类和位置，或者我认为：
in my pom.xml
在我的pom.xml
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
<configuration>
<classifier>spring-boot</classifier>
<mainClass>
app.ContactRunner
</mainClass>
</configuration>
</execution>
</executions>
</plugin>
And here's a screenshot of the project structure along with the MANIFEST.MF
