Summary of solutions for SVN to return com 'is missing or not locked during update

Use myeclipse for Java Development and SVN for version control. Update with the following error message:
Org. Tigris subversion javahl. clientexception: working copy not locked; this is probably a bug, please report
SVN: working copy 'd: \ temp \ workspace \ bobo365 \ webroot \ WEB-INF \ Classes \ com 'is missing or not locked
On the Internet, it is found that eclipse put the SRC folder. SVN folder also "compiled" to the WEB-INF/classes, and copied. SVN stores the version information in the SRC folder, causing an error during the update.

The eclipse development process is often automatically compiled and released, which leads to the corresponding folders in the/Web-INF/directory. when the svn folder is deleted together, the svn 'containing' copy admin area is missing prompt is displayed during synchronization.

Solution:

Browse the directory structure of the svn repository, delete all or part of the related files under the/Web-INF/directory under the project directory (here I only delete the classes directory), and refresh. And then perform synchronization. OK.

Open the project-> properties-> JAVA build path menu in eclipse, on the "Source" tab in the right panel, and add "**/. SVN/**" to excluded /**".
That is to say, exclude the. SVN folder from the compilation path so that the above problems will not occur.
