I was able to figure out what in my pom.xml is causing this, it's build > pluginManagement > plugins >

Falling back to 1.0-beta-1 lets tidy:pom work again.

Running into this problem too. The check goal is failing, so figure running pom goal will fix the issue -- alas, that produces the exception too, so I'm stuck and unable to upgrade.

[dennisl]

We stumbled across this as well with the following POM snippet. The error occurs on the <extension> line. This is consistent with the error that @jieryn got. It seems that the tag <extension> somehow trips up the XML parser.

      <plugin>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-xjc-plugin</artifactId>
        <version>3.0.5</version>
        <configuration>
          <extensions>
            <!-- Getters with default values if given in schema -->
            <extension>org.apache.cxf.xjcplugins:cxf-xjc-dv:3.0.5</extension>
          </extensions>
        </configuration>
        <executions>
          ...
        </executions>
      </plugin>

I'm also seeing this when executing tidy:pom on a project using the jaxb2-maven-plugin, where parameter is configured for that plugin.

[andham]

The problem lies in that we have code to sort sections in the pom, which expects a certain structure which isn't fullfilled here.

[andham]

Should be fixed by PR #13.

[tchemit]

I got this error on this pom.
I will try which pom section provoque this error.
