One pugin to contain the bulk of the code, which is independent of jdt.ls, lsp4e and lsp4j.
Second plugin to contain the jdt.ls specific DelegateCommandHandler implementation.
This should allow us to somehow re-use the bulk of the code in STS4 eclipse, i.e. when
we have access to JDT from eclipse directly, and there is no jdt.ls process around.
Use proper jdt.ls snapshot udate site instead of locally built one.
Re-enable test running in spring-boot language server.
Remove debug flags from vscode-spring-boot launcher.
To avoid confusing prefix matching between patterns like
vscode-boot-* and vscode-boot-properties-*, vscide-boot-java-*
This would pontially cause weird version strings in concourse resources.
