Grails 4 和 Views-Json 2：构建失败

Question

I'm trying to upgrade a Grails app from 3.3 to 4 (specifically 4.0.3 for now) and the Views-Json 2.0.2 plugin. Profile is angular.

When I run the app in development mode everything works. However when I attempt to build using gradlew :server-api:assemble the build fails at the Task :server-api:compileGsonViews (yeah, renamed 'server' to 'server-api' for clarity).

It looks like it's not finding my Java classes (there are a few under src/main/java ).

I've see refs to setting the classpath for the compileGsonViews, but I was undable to make it work.

Anyone with suggestions?

Running on Windows 10 with latest OpenJDK 1.8.x

Somehow I seem to have stumbled on the solution. In my build.gradle I had enabled the grails pathingJar, commenting that out allowed my war to build. However with the property commented out, I was unable to use the gradlew bootRun command as it failed due to the path being too long.

The solution (for me) was to add a build property, the build file then looks like:

def usePathing = Boolean.valueOf( System.getProperty('pathingJar', 'false') )
if (usePathing) {
  grails {
    pathingJar = true
  }
}

If I was better with gradle I think I could (maybe) determine the goal that is being targeted and use that, but the above works. The commend to assemble the war is the same; but to run the app directly I need to make it gradlew server-api:bootRun -DpathingJar=true
