"jar -ufe" Command to Create an Executable JAR
What is the "jar" command to create an executable JAR? I know the starting class name in the JAR file.
If you know the starting class name and that class is in the JAR file, you can use the "jar -uvfe jarname classname" to make JAR file as executable.
For example, I want to make myNew.jar executable with the Hello class:
\fyicenterjar>"%java_home%\bin\jar" -uvfe myNew.jar Hello updated manifest \fyicenter>"%java_home%\bin\java" -jar myNew.jar Hello new world! \fyicenter>"%java_home%\bin\jar" -xvf myNew.jar \fyicenter>type META-INF\MANIFEST.MF Manifest-Version: 1.0 Created-By: 1.8.0_45 (Oracle Corporation) Main-Class: Hello
As you can see from the output, "jar -uvfe myNew.jar Hello" command just added "Main-Class: Hello" to the MANIFEST.MF file. Of course, you can manually, edit the MANIFEST.MF file and put it in the JAR file.
