import tags without schemaLocation attribute result in FileNotFoundException #45

Open andygoossens opened 5 years ago

andygoossens commented 5 years ago

The plugin is unable to cope with import tags without a schemaLocation attribute. e.g.

<import namespace="urn:ietf:params:xml:ns:eppcom-1.0"/>

If it encounters such tag, then the build will fail with a rather undescriptive error message:

Execution failed for task ':xsd-dependency-tree'.
> java.io.FileNotFoundException: /path/to/repo/gradle-jaxb-plugin-import-issue/src/main/resources/xsd (Is a directory)

I have created a simple testcase repository to reproduce this issue. While I can work around this issue by mentioning a schemaLocation attribute, I would rather avoid that. (The XSD files were copied from RFC 5730 and diverging from those would be undesirable.)

If I would be calling the Ant task XJC2Task directly, then I would have been able to provide a catalog file which it would use to understand how the namespaces and files fit together. Unfortunately, gradle-jaxb-plugin does not seem to support that. :-(

@andygoossens Is there a reason you can't pass it as an XJC argument (e.g. -catalog <file>?

Similar to this example:

I know I can pass it as a XJC argument, but the Gradle build will fail before reaching the "xjc" task. Task "xjc" depends on "xsd-dependency-tree" and it is the latter that fails.

I have tried excluding "xsd-dependency-tree", but that won't work either:

./gradlew clean xjc -x xsd-dependency-tree
> Task :xjc FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':xjc'.
> Cannot get property 'managedNodes' on null object

@andygoossens : i have the same problem, did you find a solution ? Thank you

andygoossens commented 5 years ago

@drapej: I am not using this plugin anymore for my module that has this error. I went back to using Ant task XJC2Task.

@andygoossens : ok thank you. Is it possible to share your build.gradle with this ant task ?

@drapej: I cannot share the actual code as it can be considered to be proprietary, but it looks like this: https://stackoverflow.com/a/41880497
