Grails 7.0.1 app running as war file stopped working Steps to create: 1. Generate a Grails app from Grails forge. With sitemesh3 disabled. 2. Download the zip file and run it within the project folder and it runs fine. 3. Assemble the war with

gradle clean assembe

and run it outside the project folder. 4. The app will error out with the following exception:

Is it working using

./gradlew bootJar

?

@User I cannot reproduce this error. Could create a ticket at https://github.com/apache/grails-core/issues describing the exact command you use to run the war?

Okay. Will do. plus, let me try to reproduce with another machine. Sometime I found it is not consistent.

@Adrien Guichard @mattias_reichel confirmed, it is my environment issue, I removed ~/.grails and ~/.gradle and recompile my local test projects, it worked fine now.
