Question

If you have custom rules for the intellij ktlint plugin and they don t seem to run after you put the jar files in the ktlint ide plugin config form is there any way to debug why There are no errors in the AS IDE log either thinking face Side note would be nice if the jar list field were larger because the jar paths can be fairly long if you have multiple jars

blob thinking fast I can definitely look into improving the jar UI smile though I m not aware of any current issues with custom ruleset jars

One issue might be that we need multiple JAR files loaded found this class conflict ```Caused by java lang LinkageError loader constraint violation when resolving method boolean org jetbrains kotlin psi psiUtil KtPsiUtilKt isAbstract org jetbrains kotlin psi KtClass the class loader java net URLClassLoader 375c179b of the current class com twitter ktlint rules SerializableContentViewArgsCheck and the class loader com intellij ide plugins cl PluginClassLoader 7da6c7b3 for the method s defining class org jetbrains kotlin psi psiUtil KtPsiUtilKt have different Class objects for the type org jetbrains kotlin psi KtClass used in the signature com twitter ktlint rules SerializableContentViewArgsCheck is in unnamed module of loader java net URLClassLoader 375c179b parent loader com intellij ide plugins cl PluginClassLoader 138301aa org jetbrains kotlin psi psiUtil KtPsiUtilKt is in unnamed module of loader com intellij ide plugins cl PluginClassLoader 7da6c7b3 parent loader bootstrap at com twitter ktlint rules SerializableContentViewArgsCheck visitClassNode SerializableContentViewArgsCheck kt 23 at com twitter ktlint rules TwitterKtRule visit TwitterKtRule kt 25 ```

Probably time for me to take a step back and look for simple example ruleset jar that definitely works w the IntelliJ plugin and try adding our rules into it bit by bit

Paul Dingemans · Answer

The ktlint project contains a template for a custom ruleset

Paul Dingemans · Answer

Have you tried to run your custom ruleset with the ktlint CLI This might give a better understanding whether the problem is in the ruleset or the plugin

kenkyee · Answer

ktlint CLI works fine we use the ruleset with it we re just trying to get the custom rules working w the ktlint intellij plugin It looks like it s conflicting w some class that the IDE is also supplying from that stack trace snippet thx for the template pointer slightly smiling face

nbadal · Answer

ah yeah the IDE loves to conflict disappointed I ran into that with the plugin itself too

kenkyee · Answer

I m guessing we re going to have to shade some classes jars we use in our custom rules

nbadal · Answer

yeah give that a shot that s what I had to do to get the plugin working as well grimacing
