Update to use latest jdtls 0.30.0 milestone from 201812180348 so that we can fix this problem:

Note that this fails locally for me with:

[ERROR] The constructor CUCorrectionProposal(String, ICompilationUnit, int) is undefined

So either we need to try an older jdtls (0.29? 0.28?) or we need to fix this compilation error to use the latest 0.30.

WDYT?

[tolusha]

We have to fix compilation errors.

Note that the same missing URL failure occurs with 0.29:

[ERROR] Failed to resolve target definition /home/nboldt/.m2/repository1/org/eclipse/jdt/ls/org.eclipse.jdt.ls.tp/0.29.0.20181203134803/org.eclipse.jdt.ls.tp-0.29.0.20181203134803.target: Failed to load p2 metadata repository from location http://download.eclipse.org/eclipse/updates/4.10-I-builds/: Unable to read repository at http://download.eclipse.org/eclipse/updates/4.10-I-builds.

At first we need to solve this one eclipse-che/che#12262
