As mentioned @RaghuPrasanth V and @nitind, be sure that your version of Eclipse is working with newer versions of Java.

Because I had the same issue:

org.eclipse.e4.core.di.InjectionException: java.lang.NoClassDefFoundError: javax/annotation/PostConstruct
...
Caused by: java.lang.ClassNotFoundException: javax.annotation.PostConstruct cannot be found by org.eclipse.e4.core.di_1.6.100.v20170421-1418

using Java 11 and Eclipse Java EE IDE for Web Developers. Version: Oxygen Release (4.7.0) Build id: 20170620-1800

And to solve it, I have re-installed to:

Eclipse IDE for Enterprise Java Developers. Version: 2019-03 (4.11.0) Build id: 20190314-1200 from here.

Hi,

Add this lines at end of your eclipse.ini

Make sure that you're version of Eclipse and JDK match, either both 64-bit or both 32-bit, then set the path of the JRE in the environment .
