bazel wrapper to automatically trigger gazelle

bazel

#!/usr/bin/env bash

# Small bazel wrapper than will trigger gazelle if bazel returns a missing dependencies error.

tempfile=$($BAZEL_REAL info command_log)
$BAZEL_REAL "$@"
res=$?
if [[ $res -gt 0 ]]; then
    if grep "missing strict dependencies" $tempfile; then
        echo "Bazel failed with missing strict dependencies. Running gazelle, then rerunning."
        $BAZEL_REAL run //:gazelle
        $BAZEL_REAL "$@"
        res=$?
    fi
    exit $res

Save this as tools/bazel. All calls to bazel will automatically be replaced by this script.
