使用Maven在Grails中運行測試用例時，違反加載程序約束

Question

我正在使用maven在grails中運行測試用例，並獲得以下堆棧跟蹤。

我有以下沖突。

loader constraint violation: when resolving field "DATETIME" the class loader (instance of org/codehaus/groovy/grails/cli/support/GrailsRootLoader) of the referring class, javax/xml/datatype/DatatypeConstants, and the class loader (instance of <bootloader>) for the field's resolved type, javax/xml/namespace/QName, have different Class objects for that type

java.lang.LinkageError: loader constraint violation: when resolving field "DATETIME" the class loader (instance of org/codehaus/groovy/grails/cli/support/GrailsRootLoader) of the referring class, javax/xml/datatype/DatatypeConstants, and the class loader (instance of <bootloader>) for the field's resolved type, javax/xml/namespace/QName, have different Class objects for that type

我已經嘗試了很多，但是無法解決。

任何幫助都非常有用。

我遇到類似的問題，解決方案是排除stax-api模塊。 我使用具有以下配置的Gradle：

configurations {
compile.exclude module: 'stax-api'}

如果您使用的是Maven，我認為它是相似的。 希望能幫助到你。
