We are trying to install solr-7.3.1 into our existing system (We have also

I am having some build issues and it would be really helpful if someone can
help.
While running ant test(in the process of building the solr package), it
terminates because of failed tests.
This is a known problem. Solr's tests are in not in a good state.
Sometimes they pass, sometimes they fail. Since there are so many tests
and a fair number of them do fail intermittently, this creates a
situation where on most test runs, there is at least one test failure.
Run the tests enough times, and eventually they will all pass ... but
this usually takes many runs.
Looking at the commands you're using in your script: After a user has
run the "ant ivy-bootstrap" command once, ivy is downloaded into the
user's home directory and does not need to be downloaded again. Only
the "ant package" command (run in the "solr" subdirectory) is actually
needed to build Solr. The rest of the commands are not needed.
As Emir said, you don't need to build Solr at all, even when using
custom plugins. You can download and use the binary package.
There is effort underway to solve the problem with Solr tests. The
initial phase of that effort is to disable the tests that fail most
frequently. The second overlapping phase of the effort is to actually
fix those tests so that they don't fail - either by fixing bugs in the
tests themselves, or by fixing real bugs in Solr.
Also, does ant version has any effects in build??
Ant 1.8 and 1.9 should work. Versions 1.10.0, 1.10.1, as well as 1.10.3
and later should be fine, but 1.10.2 has a bug that results in the
lucene-solr build failing:
https://issues.apache.org/jira/browse/LUCENE-8189
At last, at present, we are using solr-6.4.2 which has zookeeper-3.4.6
dependency but for solr-7, the zookeeper dependency has been upgraded to
3.4.10, so my question is, At what extent does this might affect our system
performance? Can we use zookeeper-3.4.6 with solr-7?
(same with the jetty version)
You should be able to use any ZK 3.4.x server version with any version
of Solr. Most versions of Solr should also work with 3.5.x (still in
beta) servers. Early 4.x version s shipped with ZK 3.3.x, and the ZK
project does not guarantee compatibility between 3.3.x and 3.5.x.
I can't guarantee that you won't run into bugs, but ZK is generally a
very stable piece of software. Each new release of ZK includes a very
large list of bugfixes. I have no idea what implications there are for
performance. You would need to ask a ZK support resource that
question. The latest stable release that is compatible with your
software is the recommended version. Currently that is 3.4.12. The
3.5.x releases are in beta.
