Gretty 2.3.0 JettyScannerManager error

[acestars]

This is the configuration:

managedClassReload = false
servletContainer = 'tomcat9'
scanInterval=1
scanDir "${projectDir}/src/main"
fastReload "${projectDir}/WebContent"

every I changed the content of WebContent the JettyScannerManager throw error

org.akhikhl.gretty.JettyScannerManager$1@4f2ec1aa failed on '[path_of_directory, path_of_directory/filename]

gretty 2.2.0 works properly, no error

Thanks for the report. Which JDK and Gradle are you using, and can you please provide a minimal example project.

[boris-petrov]

I just noticed the same issue. Could it be related to #95? The new Groovy perhaps outputs some broken bytecode because of the compile error?

[javabrett]

@boris-petrov an excellent theory. I have some local commits with a fix in the works for that. If we can document a reproducible case for this, it can be tested (might just rely on scanDir or fastReload).

I already tried jdk 8 and 11. Maybe I will provide the sample project on monday.

I can reproduce this also. The problem call is at:

gretty/libs/gretty/src/main/groovy/org/akhikhl/gretty/JettyScannerManager.groovy

Line 33 in 41d081c

scanFilesChanged(filenames)

I think this is caused by Groovy bug Statically compiled calls to protected methods of an outerclass' superclass result in IllegalAccessErrors (fixed in Groovy 2.5), together with 3cb2547 which added @CompileStatic to BaseScannerManager as part of #46.

gretty/libs/gretty/src/main/groovy/org/akhikhl/gretty/scanner/BaseScannerManager.groovy

Line 15 in 41d081c

@CompileStatic(TypeCheckingMode.SKIP)

We can either remove that one @CompileStatic or compensate for the bug.
