When i upgrade the gradle version to 6, below error is coming. The samples in https://github.com/reaster/schema-gen-examples are also failing with the same error.

schemaGen {
java {
schemaURL = new URL('file:src/main/resources/atom.xsd')
packageName = 'com.sap.java'
addSuffixToEnumClass = null
anyPropertyName = 'text'
}
}

when i remove the above code, it works!!! But we need this configuration. Any help???
