Question

我正在使用Eclipse Indigo从头开始设置一个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。我甚至在整个项目中搜索文本<extension>war</并且神秘地说，在我的项目中没有这样的文本。但是，在tomcat web.xml中有很多<extension>标记，但我怀疑它在此错误中有一些操作因为我从未触及web.xml

这是我的pom.xml

正如Funtik建议的那样，我用-X进行了构建。这是堆栈跟踪。

有什么想法吗？

Answer 1

我刚刚通过从我的本地存储库中删除已安装的该版本工件来修复此问题。

对我而言，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不兼容的内容（扩展名）。因此，新安装与maven 2导致错误。

Maven的信息可能更加准确。就像包含问题的文件的文件路径一样，例如：）

Answer 2

你的问题是你的工件我有一个空间。试试这个pom：

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

Answer 3

是的，如果您有权访问您的存储库，只需删除该m2文件夹。

Answer 4

在我的情况下，问题是由于额外的空间。要修复此错误，我删除了发生错误的行上的标记之前的空格。例如，我的pom.xml在标记之前有4个空格，我删除了空格并修复了错误

Answer 5

对于遇到类似问题但仍在寻找答案的每个人：就我而言，它不是一个额外的空间，而是一个不可接受的价值。这是导致我错误的原因：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <executions>
      <execution>
        <id>default-jar</id>
        <phase>never</phase>
      </execution>
    </executions>
  </plugin>

指定值＆＃34;从不＆＃34;是不能接受的。只需使用有效值，例如＆＃34; none＆＃34;。

Answer 6

元数据已损坏，如下所示：

</versioning>
</metadata>
011</lastUpdated>
</versioning>

由于我尝试使用jenkins集中构建而不是本地构建，因此无法删除旧的元数据文件。这是我找到的解决方案：

使用Maven 3＆amp; D重新运行构建确保使用有效的xml更新元数据。然后恢复构建回Maven 2.2运行。

Answer 7

如果在Artifactory中从Maven远程请求工件时出现此错误，可以通过启用“抑制POM一致性检查”选项来解决此问题：

Answer 8

上一个标签后面有一个很小的空间，这引起了同样的问题。我遇到了</dependencies>的问题。

解决方案：删除空格（下面带有黄色标记的）确实很神奇。

在此，我附上了屏幕截图，以更正pom.xml
