Exception converting domain class in Windows

[tepsl]

In Windows, both 7 and 8.1 for x64, development mode, the exception occurs in runtime. In OS X, it never happens. Executing "grails generate-remote-domain" results in the same exception. Is there any solution or workaround? The stacktrace of "grails --verbose generate-remote-domain" is:

Thanks for reporting. Something is happening with the file system in windows machines, sadly I don't have a windows machine to test it. No solution or workaround at the moment. I need a window user to test and fix that, any takers?

This is the point of the error: https://github.com/chiquitinxx/grooscript-grails3-plugin/blob/master/src/main/scripts/generate-remote-domain.groovy#L22

By my investigation, conversionResult is null. So GrooscriptConverter.convertRemoteDomainClass() must be the matter. I'll dig into it more deeply.

Finally got a solution.

In Util.groovy, SEP is used for regex. Unfortunately SEP is backslash in Windows. Then backslash is interpreted as escape character and there's no character after backslash, so "character to be escaped is missing". Below is my workaround but there might be better solution.

    private static getFileNameFromDomainClassCanonicalName(String domainClassCanonicalName) {
        "${domainClassCanonicalName.replaceAll(/\./, SEP.replace('\\', '\\\\'))}.groovy"
    }

Cheers, thank you.

I have commited changes. Please can you update and try again? Just ./gradlew install, and use version 1.1.4-SNAPSHOT in your local windows machine. When you say is Ok, I'll release a new version.

[tepsl]

./gradlew install does not work unless the project folder is named grooscript. As I cloned this repo in my local directory as grooscript-grails3-plugin at first, ./gradlew install placed pom and jar files in %HOME%.m2\repository\org\grails\plugins\grooscript-grails3-plugin\1.1.4-SNAPSHOT and it failed.

Anyway, it works.

[chiquitinxx]

New version 1.1.4 is out.
