Using jdeps with REGEX

Question

I'm able to get the list of dependencies using jdeps: jdeps myjar.jar works fine.

Tried excluding a particular package in the output: jdeps -f 'java.io' myjar.jar - this excludes the package java.io from the output

Finally, i would like to exclude all packages that starts with the name "java" using regex:

• jdeps -f 'java' myjar.jar -> didn't work (does not filter 'java' packages)
• jdeps -f '/java/i' myjar.jar -> didn't work (does not filter 'java' packages)
• jdeps -f '^java' myjar.jar -> didn't work (does not filter 'java' packages)

Can someone help me to filter all the packages that match a given pattern?

Answer 1

Try Negative Lookahead operator !?

The regex looks like this: ^(?!java) (returning only when line doesn't start with java )

The final code looks like this: jdeps -f '^(?!java)' myjar.jar
