I use as IDE Eclipse 4.8 Photon and I have installed the Spring Tool Suite 3 Plugin Version 3.9.7.RELEASE. So far everything is fine. Then I try to import a Spring Getting Started Project with File -> New -> Spring Boot -> Import Spring Getting Started Content
After that I get a ClassCastException:
The selected wizard could not be started. Plug-in "org.springframework.ide.eclipse.boot.wizard" was unable to instantiate class "org.springframework.ide.eclipse.boot.wizard.guides.GSImportWizard". ClassCastException: attempting to castbundleresource://1458.fwk2040301400:7/javax/ws/rs/client/ClientBuilder.class to bundleresource://1573.fwk2040301400/javax/ws/rs/client/ClientBuilder.class
How could I solve this problem?
