在Eclipse Helios中构建工作区时出错

我正在使用EclipseHelios开发web应用程序，每当我启动EclipseHelios时，它都会显示以下错误

Errors occurred during the build.
Errors running builder 'Integrated External Tool Builder' on project 'MyProject'.
The builder launch configuration could not be found.
The builder launch configuration could not be found.

我在工作区中加载的项目是我的项目，我在谷歌上搜索了错误，但我没有找到有效的解决方案，请帮助我

提前谢谢
