JarScan, scan all JAR files in all subfolders for specific class

Question

We are seeing an older version of a class being used, although we had the latest one deploy. To scan all JAR files in all subfolders of an application server, how do we writ

Answer 1

Something like:

find . -name '*.jar' | while read jarfile; do if jar tf "$jarfile" | grep org/jboss/Main; then echo "$jarfile"; fi; done

You can wrap that up like this:

jarscan() {
  pattern=$(echo $1 | tr . /)
  find . -name '*.jar' | while read jarfile; do if jar tf "$jarfile" | grep "$pattern"; then echo "$jarfile"; fi; done
}

And then jarscan org.jboss.Main will search for that class in all jar files found under the current directory
