Question

当eclipse尝试构建我的工作区时，我突然开始收到错误。

Errors occurred during the build.
Errors running builder 'Faceted Project Validation Builder' on project 'pepper'.
Could not initialize class org.eclipse.jst.j2ee.project.facet.IJ2EEFacetConstants

由于我收到此错误，所有项目都没有部署到tomcat。如果我去服务器配置服务器视图 - ＆gt;右键单击 - ＆gt;打开 - ＆gt;模块选项卡。我可以在Module列中看到以下内容。

org.eclipse.jst.jee.server:<projectName> missing

我的所有项目都是如此。

我正在使用Eclipse Juno。我之前能够部署所有项目。我所做的只是从http://eclipse.org/bpmn2-modeler/安装BPMN 2.0 eclipse插件。我试图卸载它，但没有任何改变。

错误日志正在说明。

试试这个：

在依赖关系部分添加以下行：

  <dependency>
    <groupId>org.eclipse.jst</groupId>
    <artifactId>j2ee</artifactId>
    <version>1.1.105-v200709122200</version>
  </dependency>

来源：http://mavenhub.com/c/org/eclipse/jst/j2ee/project/facet/ij2eefacetconstants/dependency

由于org.eclipse.jst.jee.server：<project>缺少</project>，Eclipse juno将不会部署到tomcat 7
