An issue with Eclipse's export failure

When you export a project as a jar or executable program with Eclipse, you often encounter problems with export failures. There are generally two (with solutions) for this reason:

1. Accidentally deleted the class under Bin, resulting in a class not found. There are two solutions:

(1) Click Project--->clean---->clean project Selected below, select your project---->ok.

(2) Create a new project directly, re-copy the original documents back.

2. Frequent additions and deletions, frequent expoert,eclipse too late bulder. Solution: If it is frequent export caused, generally over time oneself will be good, eclipse jar protection mechanism will automatically unlock, no tube. If it is caused by frequent additions and deletions, then the solution is the same as 1
