Unbound classpath container in Eclipse

Question

I have checked out a project using Subversive for Eclipse and I am getting the following errors:

• The project cannot be built until build path errors are resolv

Answer 1

For those using sdkman, this helped me.

Use Case:
I was using identifier 8.0.202-amzn
I decided to install Azul Zulu as follows: sdk install java 13.0.2-zulu

Error: And then i got this unbound error.

Solution:
1. Right-click on your project in Eclipse/STS
2. Choose Build Path > Configure Build Path...
3. Under Libraries, remove the JRE Library, for my case 8.0.202-amzn
4. Under Libraries, click on Modulepath > Add Library...
5. Choose JRE System Library, click Next
6. Choose Alternate JRE, click on Installed JREs...
7. Your previous configured value should be there
8. If it is there, edit it, if it is not there, add one
9. Make sure the name is: 13.0.2-zulu
10. And the location(JRE home) is: /Users/jumping_monkey/.sdkman/candidates/java/current
11. Click Apply and close
12. Click Finish
13. Voila!

You will see JRE System Library [13.0.2-zulu] in your Project Explorer and all errors gone

Bravo!
