错误：没有这样的文件或目录试图从终端创建 jar 文件

Question

I have performed the following steps:

• A single java file called ComputeArray.java, with no specified package
• Navigated into the folder containing the program
• Created the class file (and it runs)

The command I am having trouble with is as follows:

• jar cvf computearray.jar ComputeArray.class

And I have tried using a manifest with cvmf and also tried adding ComputeArray.java at the end. I always end up with the same error "no such file or directory

Answer 1

You also have to specify the manifest file while creating jar file, something like:

$ jar cmf Hello.mf Hello.jar Hello.class Hello.java
