How can I add imported jar files to web-inf/lib in eclipse for my build?

Drop the jars that need to be in the classpath of the deployed webapp (in WEB-INF/lib) under the WebContent/WEB-INF/lib product of the Eclipse project. That's all you need to do.

If you already added them to the project's build path, then remove them from there: everything under WebContent/WEB-INF/lib is automatically added to the build path.

eclipse ide: tomcat deletes my jar file in WEB-INF/lib

You put jar files in the target directory of Eclipse, i.e. in the directory that is generated and populated by Eclipse when building the webapp. So of course, each time Eclipse deploys the webapp, it cleans this directory, and deploys the new version.

You should put the jar file in your source project tree, under WebContent/WEB-INF/lib. The jars in this directory will be part of the webapp's build path automatically, and will be copied to the target WEB-INF/lib directory at deployment time by Eclipse.
