Hi there: I export a project into jar like this "right click my project->choose export ->java-> jar file-> next->choose "src/main/resouces" and ''src/main/scala"'-> clikc browse and choose a jar file export location-> choose overwrite it", and this jar is unable to run with "java -jar myjar.jar". It says "no main manifest attribute, in /opt/MyJar.jar". It seems the file MANIFEST.MF lost the main class info when I export the jar. I opened the MANIFEST.MF in my exported jar, and finds only below info:Manifest-Version: 1.0
However I checked the MANIFEST.MF in my project, it is like this:Manifest-Version: 1.0 Main-Class: org.abc.spark.streaming.Producer Class-Path: lib/spark-core_2.10-1.6.1.jar ........... in my class of producer, I didn't use spark, so I use java -jar to run it. I also tried to export my project as a runnable jar, but my class can not be run as a java application, the run button is not able to click. So could anyone share a hand? -------------------------------- Thanks&Best regards! San.Luo
