java - Maven 错误 - 预期的 START_TAG 或 END_TAG 不是 TEXT

Question

我正在使用 Eclipse Indigo 从头开始​​设置 spring mvc web 应用程序 + hibernate jpa + maven。在进行 Maven 构建时，我遇到了这个错误。

[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Error installing artifact's metadata: Error installing metadata: Error updating group repository metadata

expected START_TAG or END_TAG not TEXT (position: TEXT seen ...<extension>war</... @13:25) 
[INFO] ------------------------------------------------------------------------

我尝试使用谷歌搜索，但找不到适合我的解决方案。我什至在整个项目中搜索文本 <extension>war</神秘的是，我的项目中没有这样的文字。但是，在 tomcat web.xml有很多<extension>标签，但我怀疑它与此错误有关，因为我从未接触过 web.xml

这是我的pom.xml

    </dependencies>

    <build>

    </build>
</project>

正如 Funtik 所建议的，我使用 -X 进行了构建。这是堆栈跟踪。

有什么想法吗？

Answer 1

我刚刚通过从本地存储库中删除该版本的已安装 Artifact 来解决此问题。

对我来说，原因似乎是从 maven 3 降级到 maven 2。由 maven 3 安装的本地存储库中的 maven 元数据 xml 包含与 maven 2 不兼容的东西(扩展名)。因此，新安装使用 maven 2 导致错误。

Maven 的信息可能更准确。就像包含问题的文件的文件路径，例如:)
