You have probably done already step 1 and 2 bust just in case i mention them.

1)

Eclipse -> Window -> Preferences -> Java -> Installed JREs -> Add -> then select the java version that you would like to add.

 

2)

Go to package explorer -> right click on project -> properties -> java build path -> double click on your current JRE System library -> Select alternate JRE and point to the jdk that you added before. 

 

3) 

Go to your project -> right click on build.xml -> Run as -> External tools configurations ->JRE -> Separate JRE -> then select the one that you added and click apply/run.

Exists the easy way:

 

1. Download Eclipse.
2. Unpack Eclipse in separated folder.
3. In side this folder make new folder with name "jre".
4. Download OpenJDK 17 or another version.
5. Unpack OpenJDK into this folder.
6. All Java projects what will added into workbench in future will use this Java version as default.

In profit you can use separated Eclipse version for any Java version and not need to install into the system Java.
