jar conflict, class conflict detection script

The idea is very simple, untied war bag, untied jar package and found that they reported the same name package.class out, regardless of whether or not "compatible" ..

 

import zipfile
import io
from collections import defaultdict
import sys

if len(sys.argv) < 2:
    print("{0} /path/xxx.war".format(sys.argv[0]))
    exit(1)

exit_code = 0
jar_classes = defaultdict(set)
war_file = zipfile.ZipFile(sys.argv[1], "r")

for jar_file in war_file.infolist():
    if jar_file.filename.endswith(".jar"):
        jar_content = io.BytesIO(war_file.read(jar_file))
        jar_zip_file = zipfile.ZipFile(jar_content, "r")
        for jar_item in jar_zip_file.infolist():
            if jar_item.filename.endswith(".class"):
                class_full_name = jar_item.filename
                jar_classes[class_full_name].add(jar_file.filename.split("/")[-1].strip())

for class_full_name in sorted(jar_classes.keys()):
    jar_filename_set = jar_classes[class_full_name]
    if len(jar_filename_set) > 1:
        exit_code = 1
        class_full_name = ".".join(class_full_name.replace("/", ".").split(".")[:-1])
        print("{1}\t{0}".format(class_full_name, ", ".join(jar_filename_set)))

war_file.close()
exit(exit_code)
