如何更新 .ear 文件中的 .jar 文件并使用 bash 脚本保存 .ear 文件

Question

How to update a .jar file inside .ear file and save the .ear file using bash script?

The flow works like below:

I have an older.ear (located at Documents/older.ear)
that contains older.ear/APP-INF/libs/updateme.jar &
I have a updateme.jar file (located at Documents/libs/updateme.jar), 
which needs to be updated to older.ear/APP-INF/libs/updateme.jar, 
then the ear file has to be saved.

As of now, I am been using 7zip , but would like to have it automated with a bash script.

Answer 1

An EAR file is simply a zip file, so you should:

1. Unzip the EAR file by 7z .
2. Replace the JAR file.
3. Recreate the EAR file by 7z .

The instructions to accomplish this are trivial, you can write them on your own.
