Class 'myClassName' already exists in package 'myPackageName'

阅读更多关于 Class 'myClassName' already exists in package 'myPackageName'

问题 I suddenly started facing a strange issue while working on my Grails application using IntelliJ. I have different domain classes and some other classes under src/groovy . When I open a class file to make some changes, I get an error that this class already exists in package which I don't have. I tried to rename the class using refactor but after that I still get the same error. Can anybody suggest what's wrong here or if I did something wrong? 回答1: Try to "Clear" you project and build again.

compileAssets failing on upgrading Grails application

阅读更多关于 compileAssets failing on upgrading Grails application

问题 I have a Grails application running version 3.3. I recently upgraded to version 4.0.3. The way I typically upgrade, which I understand is probably not the best way, is to upgrade my environment to the new Grails version, then create a brand new Grails project (I'm using IntelliJ), and then slowly move my files over from the old project to the new project, fixing things as I find they don't work. I have everything moved over and the app works perfectly while running run-app inside IntelliJ.

Grails 4.0.1 - Spock unit test cases fail because of spaces

问题 I am testing i18n formatting using unit tests in my Grails 4.0.1 application but seeing strange results. To me, this specs condition should be satisfied, but it is not. I don't suppose anyone has had a similar experience that can be explained, or maybe it's simply a bug? Any help would be appreciated. 回答1: Just as an idea: Can you iterate over both expected and actual values and convert the characters one by one to the ascii so that you'll probably see the difference for( c in '123 456,78 $'
