How to solve “This element has no attached source and the Javadoc could not be found in the attached Javadoc”?

Question

I don\'t get the exact method to do this. I want a method not for a single project for all projects in eclipse. Please tell me how to solve this problem.

Answer 1

To Solve this issue for all projects, the best way is to create a user library and import all your external JARs into that library. Then for each JAR add the javadoc URL into Javadoc location field. So this way whenever you need to import the JARs under build path, always use user library. so you will have javadoc location already configured.

Answer 2

This problem happened to me also when I upgrade to Eclipse Photon version. Use this following flow to attach Javadoc manually.

Go to Eclipse >> Window >> Preferences >> Java >> Installed JREs >> Select "JRE" and Edit >> Choose "C:\Program Files\java...\lib\jrt-fs.jar" >> Choose "Source attachment" and Source attachment... >> Choose External location >> Go to the path of "src" like "C:/Program Files/Java/jdk-10.0.1/lib/src.zip" >> Ok >> Finish >> Apply and Close.

Assuming you're using Eclipse as an IDE, the statement (provided in your question title) means that the IDE cannot find a javadoc comment to display the method/class/attribute description (usually shown when hovering a class/method/attribute). To fix this, you need to attach a jar or zip that contains the javadoc comment. This is usually a source code for a specified class (as it contains comments, if the programmer provided comments) and the IDE will extract the javadoc comments out of it and display it appropriately.

Hope this helps.
