Jython环境安装pdfminer失败，寻求Python与Maven Java项目集成方案

尝试将Python脚本与基于Maven的Java项目集成，原本计划通过Jython环境安装pdfminer模块实现，但多次操作均失败，具体记录如下：

失败操作及错误信息 #

1. 在线安装pdfminer #

执行命令：

C:\Users\lordonez\.m2\repository>java -jar C:\Users\lordonez\.m2\repository\org\python\jython-standalone\2.7.2rc1\jython-standalone-2.7.2rc1.jar -m pip install pdfminer-20191010

返回错误：

DEPRECATION: A future version of pip will drop support for Python 2.7.
Collecting pdfminer-20191010
  ERROR: Certificate did not match expected hostname: pypi.org. Certificate: {'notAfter': 'May 30 18:53:39 2024 GMT', 'subject': ((('commonName', 'www.python.org'),),), 'subjectAltName': (('DNS', 'www.python.org'), ('DNS', '*.python.org'), ('DNS', 'docs.python.org'), ('DNS', 'downloads.python.org'), ('DNS', 'pypi.python.org'))}

2. 本地安装压缩包（tar.gz/zip） #

执行tar.gz包安装命令：

C:\Users\lordonez\.m2\repository>java -jar C:\Users\lordonez\.m2\repository\org\python\jython-standalone\2.7.2rc1\jython-standalone-2.7.2rc1.jar -m pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org C:\Users\lordonez\.m2\repository\org\python\jython-standalone\2.7.2rc1\pdfminer-20191010.tar.gz

返回错误：
