我正在尝试使用org.python.*库（又名 jython）在 Java 中运行 python v3 脚本

import org.python.util.PythonInterpreter;
...
@Test
public void test() throws Exception {

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    MapUtils.debugPrint(new PrintStream(baos), "ENV:" , System.getenv());

    // This just shows that JYTHONPATH and PYTHONPATH are in my system env.

    log.debug("System.getenv(): {}", new String(baos.toByteArray(), StandardCharsets.UTF_8));

    try(PythonInterpreter pyin = new PythonInterpreter()) {
        pyin.execfile(JYTHON_PY.toString()); // <--- fails here due to module missing.
    }

}

JYTHONPATH=$PYTHONPATH mvn compile test-compile -pl RMBN-Service surefire:test@jython

org.python.core.PyException: ImportError: No module named sysrepo

我目前运行上述行以确保设置了 JYTHONPATH 变量，但这也不起作用。（基于此处的建议：https ://www.stefaanlippens.net/jython_and_pythonpath/ ）

但是，在我的脚本中，我需要位于我的 $PYTHONPATH 系统变量中的模块，但是 PythonInterpreter 没有使用该 PYTHONPATH（也不是 JYTHONPATH）变量。

我的版本：

  • JDK 8
  • MVN 3.6
  • org.python - jython-standalone - 2.7.2

还有我的相关系统环境：
