我正在寻找方法来检查哪些Jenkins插件没有使用。到目前为止，我发现我可以在 * config.xml * 文件中查找带有属性 plugin 的标记，然后将它们与 plugins 目录中列出的标记进行比较。但这并不能给予我完整的清单。还有一些不存在，比如“角色战略”。
我使用如下的Python代码

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import sys
import glob
from lxml import etree as ET
from collections import defaultdict

def find(name, path):
    return glob.glob(path+'/jobs/*/'+name)

def get_plugin_list(path):
    return [x[:-4].split('/')[-1] for x in glob.glob(path+'/plugins/*.jpi')]

if __name__ == "__main__":
    jobs_dict = defaultdict(list)
    plugins_all = set(get_plugin_list('/home/user/.jenkins')
    for config in find('config.xml', '/home/user/.jenkins'):
        with open(config) as f:
            tree = ET.XML(f.read())
            plugins = tree.xpath("/project//@plugin")
        job = config.split('/')[-2]
        for p in plugins:
            jobs_dict[p].append(job)
    with open('/home/user/.jenkins/config.xml') as f:
        tree = ET.XML(f.read())
        plugins_config = tree.xpath("/hudson//@plugin")
    plugins_used = set([x.split('@')[0] for x in jobs_dict.keys()+plugins_config])
    print "######## All plugins\n", '\n'.join(plugins_all)
    print "######## Used plugins\n", '\n'.join(plugins_used)
    print "######## Unused plugins\n", '\n'.join(plugins_all - plugins_used)
