Tomcat publishes a project that can't run

Projects that often appear on the job will run well and not be updated with the code from SVN

The problem sometimes is because the compilation is unsuccessful and the process steps are as follows:

1.clean entire project, recompile

2. If not, set the compile as error to warning, for example myeclipse:

Click the menu bar window----Preferences, select Java---Compiler----Building in the popup dialog box, and then expand build path problems, Select the expanded option as warning or ignore, then click OK
