Ant target fails then imported into gradle

Hey,

I posted here the same problem with example, explanation and current fix.

Issue when executing XJC Ant task through Gradle - ClassNotFoundException

Hello all, we had an ClassNotFoundException happening after executing XJC Ant task through Gradle. And we managed to find the root cause for this and it’s in the JAXB implementation. That implementation closes ClassLoader (ant-loader) from Gradle and prevents from loading new classes. Issue for that is opened: https://github.com/eclipse-ee4j/jaxb-ri/issues/1391 I’m writing this here just in case somebody from the community has the same issue and to save them the trouble of debugging ClassLoad…

It’s the issue with JAXB/XJB library and issue is reported: XJC task is closing wrong ClassLoader - ClassNotFoundException · Issue #51 · eclipse-ee4j/jaxb-istack-commons · GitHub

If you execute:

./gradlew generate_xsd --full-stacktrace --debug

You will get something like:

[DEBUG] [org.gradle.api.internal.project.ant.AntLoggingAdapter] Could not load class (org.apache.tools.ant.taskdefs.Replace) for type replace

We solved it with downgrading JAXB/XJC libraries until this is fixed. You can check GitHub - aspevec/xjc_ant_gradle: Repository for simulating bug in XJC implementation for example and more explanations.
