Hi. I'm trying to use Python extensions with Nifi. I've uncommented the line   nifi.python.command=python3   in nifi.properties but Nifi always crash when I try to run it.   When I re-comment the line, Nifi starts and works fine.   I've read this thread  https://community.cloudera.com/t5/Support-Questions/Nifi-2-0-0-M1-Installation-error-with-python/m-p/381430 and tried to follow the instructions in the solutions. It still crashes.   I'm posting here because the problem is on Windows instead of Linux.   Thanks for your help!   OS Windows 10 home edition Nifi version nifi-2.0.0-M2 Java installed version 21.0.2 Python installed version 3.11.8       nifi.properties In   nifi.properties   I changed the line from   nifi.python.command=python3   to   nifi.python.command=python   Venv I made sure the python venv package is installed by issuing this command   python -m venv which gave this message usage: venv [-h] [--system-site-packages] [--symlinks | --copies] [--clear] [--upgrade] [--without-pip] [--prompt PROMPT] [--upgrade-deps] ENV_DIR [ENV_DIR ...] venv: error: the following arguments are required: ENV_DIR showing that venv is installed   Java version java --version java 21.0.2 2024-01-16 LTS Java(TM) SE Runtime Environment (build 21.0.2+13-LTS-58) Java HotSpot(TM) 64-Bit Server VM (build 21.0.2+13-LTS-58, mixed mode, sharing)     Python version python --version Python 3.11.8     The java_home env variable echo %java_home% C:\Program Files\Java\jdk-21     python3 python3 does not work. There is no python3 command in the python installation folder. Only a .dll : dir C:\Users\ASUS\AppData\Local\Programs\Python\Python311 <DIR> DLLs <DIR> Doc <DIR> include <DIR> Lib <DIR> libs       LICENSE.txt       NEWS.txt       python.exe       python3.dll       python311.dll       pythonw.exe <DIR> Scripts <DIR> tcl <DIR> Tools       vcruntime140.dll       vcruntime140_1.dll   That's why I changed the line to   nifi.python.command=python   in nifi.properties     The work/python folder Nothing was copied to the ./work/python/controller/bin folder. The folder is not even existing.     nifi-bootstrap.log 2024-03-04 14:06:43,388 INFO [main] org.apache.nifi.bootstrap.RunNiFi {javaVersion=21.0.2, availableProcessors=12, minimumHeapSize=1g, maximumHeapSize=1g} 2024-03-04 14:06:43,426 INFO [main] org.apache.nifi.bootstrap.Command Starting Apache NiFi... 2024-03-04 14:06:43,426 INFO [main] org.apache.nifi.bootstrap.Command Working Directory: C:\Users\ASUS\Desktop\m 2024-03-04 14:06:43,427 INFO [main] org.apache.nifi.bootstrap.Command Command: C:\Program Files\Java\jdk-21\bin\java.exe -classpath C:\Users\ASUS\Desktop\m\.\conf;C:\Users\ASUS\Desktop\m\.\lib\jcl-over-slf4j-2.0.11.jar;C:\Users\ASUS\Desktop\m\.\lib\jul-to-slf4j-2.0.11.jar;C:\Users\ASUS\Desktop\m\.\lib\log4j-over-slf4j-2.0.11.jar;C:\Users\ASUS\Desktop\m\.\lib\logback-classic-1.4.14.jar;C:\Users\ASUS\Desktop\m\.\lib\logback-core-1.4.14.jar;C:\Users\ASUS\Desktop\m\.\lib\nifi-api-2.0.0-M2.jar;C:\Users\ASUS\Desktop\m\.\lib\nifi-framework-api-2.0.0-M2.jar;C:\Users\ASUS\Desktop\m\.\lib\nifi-nar-utils-2.0.0-M2.jar;C:\Users\ASUS\Desktop\m\.\lib\nifi-per-process-group-logging-2.0.0-M2.jar;C:\Users\ASUS\Desktop\m\.\lib\nifi-properties-2.0.0-M2.jar;C:\Users\ASUS\Desktop\m\.\lib\nifi-property-utils-2.0.0-M2.jar;C:\Users\ASUS\Desktop\m\.\lib\nifi-python-framework-api-2.0.0-M2.jar;C:\Users\ASUS\Desktop\m\.\lib\nifi-runtime-2.0.0-M2.jar;C:\Users\ASUS\Desktop\m\.\lib\nifi-server-api-2.0.0-M2.jar;C:\Users\ASUS\Desktop\m\.\lib\nifi-stateless-api-2.0.0-M2.jar;C:\Users\ASUS\Desktop\m\.\lib\nifi-stateless-bootstrap-2.0.0-M2.jar;C:\Users\ASUS\Desktop\m\.\lib\slf4j-api-2.0.11.jar -Xmx1g -Djava.awt.headless=true -Xms1g -Djavax.security.auth.useSubjectCredsOnly=true -Dsun.net.http.allowRestrictedHeaders=true -Djava.protocol.handler.pkgs=sun.net.www.protocol -Dcurator-log-only-first-connection-issue-as-error-level=true -Dnifi.properties.file.path=C:\Users\ASUS\Desktop\m\.\conf\nifi.properties -Dnifi.bootstrap.listen.port=52900 -Dapp=NiFi -Dorg.apache.nifi.bootstrap.config.log.dir=C:\Users\ASUS\Desktop\m\bin\..\\logs org.apache.nifi.NiFi  2024-03-04 14:06:43,433 WARN [main] org.apache.nifi.bootstrap.Command Failed to set permissions so that only the owner can read pid file C:\Users\ASUS\Desktop\m\bin\..\run\nifi.pid; this may allows others to have access to the key needed to communicate with NiFi.

I'm trying to create a new Nifi custom processor. I'm following instructions given on 4 differents tutorials. I only create the structure of the processor, I don't even try to modifiy the code and I'm always having the same mvn clean install [ERROR]. Can you please help me to resolve this ? A huge thanks!!!

Jdk in installed and I have added its bin to the path env var. JAVA_HOME env var is defined as C:\Program Files\Java\jdk-21, where my jdk is installed.
