jarsigner "Only one alias can be specified"

Question

posted Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

In Windows command prompt:

>keytool -genkey -alias me
>keytool -selfcert -alias me
>jarsigner myJar.jar me
Only one alias can be specified

I have failed to find any info on this error on the web. I'm obviously only specifying one alias here. What could I be doing wrong?

I was getting the same error.

I resolved it by renaming the folders in my path

c:his is a folder replaced with c:his_is_a_folder

jarsigner doesn't like spaces in folders
