添加属性元数据时出现异常

Question

我们正在使用以下代码将 属性元数据 添加到 MarkLogic 中的文档，但我们收到 javax.xml.bind.DatatypeConverter 异常。

DocumentMetadataHandle documentMetadataHandle = new DocumentMetadataHandle();
documentMetadataHandle.getProperties().put("test", "test");
XMLDocumentManager xmldocMgr = client.newXMLDocumentManager();
xmldocMgr.write("/test/sample", metadataHandle, domHandle);

我们使用的是 MarkLogic 10.0.-2.1，Java 客户端 API 版本是 4.1.0

例外是

请帮助我们解决这个问题。

Answer 1

编译使用的是什么Java版本？

Java 的最新版本已将 JAXB（包括数据类型转换器例程）移出核心 Java 库并移至可选的下载库中。

下面是如何使用 Gradle 添加这些依赖项的示例：
