Project configuration is not up-to-date with pom.xml. Run Maven->Update Project or use Quick Fix.

when right click and click update project and error popup displayed saying,

An internal error occurred during: "Updating Maven Project". org/eclipse/m2e/wtp/WTPProjectsUtil

anybody knows how to fix this problem, please.

Answer 1

从首选项>键入'wtp'>取消选择所有选项，然后再次构建和清理

Answer 2

What version of Eclipse? I got this error in RAD 8.5 (based on Exlipse 3.6.3). You might just need to back rev your m2e plugin. See the answers to this question: NoClassDefFoundError org.eclipse.m2e.wtp.WTPProjectsUtil upon Maven build Eclipse

I followed the link to the developer works forum and chose the 2nd option presented there:

• assuming you have m2e 1.4 (from release-for-indigo repository )
• uninstall m2e-wtp 1.x version
• and install m2e-wtp 0.18.0 (from p2 juno snapshot repo )

Answer 3

Somewhat similar solution suggested by "pppeater" - below is for Eclipse Juno

• Remove all the jars starting with "org.eclipse.m2e." from eclipse/ide/plugins folder
• From your Eclipse Market Place search for "m2e-wtp" - install "Maven Integration for Eclipse WTP (Juno) 1.0.1
• Restart your eclipse and select your project and do "Update Maven dependencies (Alt+F5)"
