Apache nifi registry in windows 10

Hi All:

I'm new to Apache NiFi. I am able to download and have the apache nifi working perfectly but when it comes to apache NiFi registry, I am getting an error preventing me to start the registry.

 

I ran the batch file after adjusting the port for NiFi registry.

run-nifi-registry.bat

 

it gave me an error. I'm guessing some classpath setup issue... not sure

 

C:\Apache nifi-1.12.1\nifi-registry-0.8.0\bin>run-nifi-registry.bat
cmd.exe /C "C:\Program Files\AdoptOpenJDK\jdk-8.0.242.08-hotspot\bin\java.exe" -cp C:\Apache nifi-1.12.1\nifi-registry-0.8.0\bin\..\conf;C:\Apache nifi-1.12.1\nifi-registry-0.8.0\bin\..\lib\*;C:\Apache nifi-1.12.1\nifi-registry-0.8.0\bin\..\lib\shared\*;C:\Apache nifi-1.12.1\nifi-registry-0.8.0\bin\..\lib\bootstrap\* -Xms512m -Xmx1024m -Dorg.apache.nifi.registry.bootstrap.config.file=C:\Apache nifi-1.12.1\nifi-registry-0.8.0\bin\..\conf\bootstrap.conf org.apache.nifi.registry.NiFiRegistry run
Error: Could not find or load main class nifi-1.12.1\nifi-registry-0.8.0\bin\..\conf;C:\Apache

You can run NiFi-Registry on Windows.
The exception you are see is related to being unable to load a class that is included with NiFi-Registry.

Maybe your download is no good.  Did you try downloading the NiFi-Registry package again?
Make sure you purge the work directory that was created by NiFi-Registry when the service attempted to start.  Make sure you did not run out of disk space.

You'll also want the product installation directory path and the directory path for the java JDK being used to NOT have spaces in the directory names. 

Use "Apache-nifi-1.12.1" instead of "Apache nifi-1.12.1".
Reinstall your JDK outside of "Program Files".

The above changes and checks should get you up and running successfully.
