When I try to run application jar using the command line on macOS, I get this error " no main manifest attribute, in ...." I try these solutions, but no one of them seems to work : You should have been used this  java -jar app.jar instead of this  java -jar "app" java - cp your . jar Mainclass. Export you Java Project as an  Runnable Jar file  rather than Jar. A manifest is a file in the path META-INF/MANIFEST.MF within the jar which defines attributes like the classpath and the main class for running the jar file.  had the same problem. Make sure your MANIFEST.MF is in: src / main / resources / META_INF / NOT src / main / java / META_INF / the only thing that works for me by using maven as follow: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <configuration> <version>3.0.2</...
