Error when importing project from SVN

The project detected from SVN will report an error, which may be the reason that all the jar packages required by the project are not imported, or it may be the encoding problem. The
encoding problem is solved: right-click the project, click to enter Properties>Resource>Other>Change the encoding format It can be UTF-8.
Solution to the jar package problem (how to check which jar packages are not imported in the project):
1. Right-click the project build path > Libraries > Add JARs 2. Add JARs
> Project detected from SVN > WebRoot > WEB-INF > If it appears jar packages, import these jar packages. If there is no jar package, it means that the imported jars in the project have been imported.
