I have jar file with manifest in it
Manifest-Version: 1.0
Build-Jdk: 1.7.0_67
Created-By: Apache Maven 3.2.3
Main-Class: com.company.main.Main
If you're not using the -jar option then you need to specify the main class to run, as the manifest will not be interrogated:
java -cp C:\commons-lang3-3.3.2.jar;.\myJar-1.0.0.jar com.company.main.Main
The classpath (-cp) option is ignored if using the -jar option (in that case the manifest should reference any other required jars via its classpath directive).
