我正在尝试使用大量使用 XML 数据等的库。我尝试使用 Maven Assembly 将我的项目编译成一个 uber-JAR，但在运行和执行一些操作后，我遇到了以下错误。

我尝试使用 Shade 进行组装，但出现了关于错误 list 签名的奇怪错误。有人遇到过这种情况吗？
最佳答案
通过将 org.codehaus.woodstox:wstx-api:3.2.9 包含到 jar 中并运行它来解决:
java -jar -Djavax.xml.stream.XMLEventFactory=com.ctc.wstx.stax.WstxEventFactory -Djavax.xml.stream.XMLInputFactory=com.ctc.wstx.stax.WstxInputFactory -Djavax.xml.stream.XMLOutputFactory=com.ctc.wstx.stax.WstxOutputFactory caeserver/target/caeserver-0.1-jar-with-dependencies.jar
关于java - 使用 Maven Assembly Plugin 时，XFire NamespaceURI 不能为空，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19606914/
