Compiling with gradle produces an error

Running python src/python/localrun.py -source wikimedium10k produces the following error for me:

Compile:
compile lucene:core...
    [RUN: ./gradlew lucene:core:jar, cwd=/.../lucene_bench_home/patch]
  /.../lucene_bench_home/patch/lucene/benchmark
Traceback (most recent call last):

    taskPatterns = (self.onlyTaskPatterns, self.notTaskPatterns), randomSeed = self.randomSeed)
  File "/.../lucene_bench_home/util/src/python/searchBench.py", line 46, in run

    cp = self.classPathToString(self.getClassPath(competitor.checkout))
  File "/.../lucene_bench_home/util/src/python/benchUtil.py", line 935, in getClassPath
    return self.getAntClassPath(checkout)
  File "/.../lucene_bench_home/util/src/python/benchUtil.py", line 893, in getAntClassPath
    for filename in os.listdir('%s/lucene/build/core' % path):
OSError: [Errno 2] No such file or directory: '/.../lucene_bench_home/patch/lucene/build/core'

Commenting these lines in src/python/benchUtil.py seems to fix an error for me:

def getClassPath(self, checkout):
     path = checkoutToPath(checkout)
+    #if not os.path.exists(os.path.join(checkout, 'build.gradle')):
+    #  return self.getAntClassPath(checkout)

@msokolov I am wondering if you can suggest a proper way to fix this issue 🙏

I think it was quite premature to change luceneutil to use the gradle build. Lets revert that, ehh?

I don’t think it is premature.

The primary purpose of luceneutil is to run correctly on Lucene’s master branch.

8.x (and prior releases) are nice to have.

But I do agree, it is a very strong nice to have for the current (8.x, now) stable branch.

So I think we should get both gradle (master) and ant (8.x) working now.

@mayya-sharipova can we resolve this issue now?
