Answer 1

Eclipse is facing some bugs in IDE 4.7 it is not fully compitable with JDK 9 like in with JDK 9 IDE is not generating toString() function also...

so i change the JDK 9 to jdk 8.1 and it solves all the problem.

to change the JDK...

Window > Preferences > Installed JREs >>> Change the JDK 9 to JDK xx

AND/OR

Right Click Project > Properties > JRE > Edit >>> YOUR ALTERNATIVE JDK xx

This had solved my problem.

Just mention, in Eclipse Version: 2020-03 (4.15.0) " Installed JREs" is located under the "Java" menu point. So, the path to making the aforementioned changes is the following: Window > Preferences >Java >Installed JREs. – Corey

@Corey Indeed thanks for update this comment really helps. – Megaton

Answer 2

I have encountered the same problem with you.
Download javax.annotation.jar online and add to your library may help.

Answer 3

If you're using maven managing your dependencies, you can also add the below dependency in your pom.xml.

<dependency>
    <groupId>javax.annotation</groupId>
    <artifactId>javax.annotation-api</artifactId>
    <version>1.3.2</version>
</dependency>

OR download the jar file from here https://mvnrepository.com/artifact/javax.annotation/javax.annotation-api/1.3.2

Or go to : right click your project->build path->configure build path->add external JARs->"C:\Program Files\Apache Software Foundation\Tomcat 9.0\lib\annotations-api.jar" and all will be right.
