javadoc:aggregate deletes product target folder

I can "mvn clean install" to gener开发者_运维百科ate zip file of my multi-project application in target folder of my product project. I can run "mvn clean javadoc:aggregate" to generate javadocs. no problem up to generating both...

When I run "mvn clean install javadoc:aggregate" javadoc is created but product zip is created and deleted.

I have tried to run mvn again but:

• "mvn clean install" generates product but deletes my javadoc target folder
• "mvn clean javadoc:aggregate" generates javadocs but deletes my product target folder.

What could be the reason? Any workaround?
