Hi,
You probably have a stale Ivy lock file in ~/.ivy2/cache/, very likely orphaned
as a result of manually interrupting the Lucene/Solr build, e.g. via Ctrl-C.
You can find it via e.g.: find ~/.ivy2/cache -name ‘*.lck’
Once you have found the stale lock file, manually deleting it should allow the
build to start working again.
FYI, LUCENE-6144[1] upgraded Lucene/Solr’s Ivy dependency to 2.4.0, and as part
of that upgrade, switched the build’s lock strategy[2] from “artifact-lock” to
“artifact-lock-nio”. As a result, in branch_5_5, branch_6_6, branch_7* and
master, ‘*.lck’ files are expected to be present all the time in the Ivy cache,
and their presence will not cause the build to fail. More info on IVY-1489[3].
