I am using IntelliJ IDEA 12.1.3. I have one module and I am trying to convert it into a jar as per the steps given here. I built the jar file and I moved the jar file to D:/. If I try to run this jar I get the following message:
Failed to load Main-Class manifest attribute from jar
If I run it using java -classpath jar com.code.TestCase it works perfectly.
Why does this happen? I created the jar using IntelliJ IDEA. In that jar it has all the code for all external libraries which I added.
In the src manifest file:
Manifest-Version: 1.0
Main-Class: com.code.TestCase
but the jar's manifest file content is:
Manifest-Version: 1.0
Build-Jdk: 1.6.0
Built-By: ubuntu
Created-By: Apache Maven
Archiver-Version: Plexus Archiver
Name: org.apache.log4j
Implementation-Vendor: "Apache Software Foundation"
Implementation-Title: log4j
Implementation-Version: 1.2.15
Why is Main-Class not added in the jar file MANIFEST.MF, but it has Main-Class in src?
