-----------------------------------------

Hello [~sarkaramrit2@gmail.com] , I resolved conflicts a little, and launched windows script. Here's what I have

At first I added -v -V and examine output. This one make sense 
GC_LOG_OPTS = "-Xlog:gc*:file=\"data\logs\solr_gc.log\":time,up

This one looks odd 

SOLR_DATA_HOME = data\data\data

Here's what I have in Solr Admin. Shouldn't tmp folder moved to writable home

-Djava.io.tmpdir=lucene-solr\solr\server\tmp

That's odd

-Dsolr.data.home=data\data\data

This is ok 

-Dsolr.log.dir=data\logs

-Dsolr.solr.home=\lucene-solr\solr\server\solr

-Xlog:gc*:file="data\logs\solr_gc.log":

!image-2019-08-28-23-57-39-826.png!

I'm not sure if this is expected behavior. 

Also usage prompt seems vague to me 

-w dir Solr will create all writable directories and files relative to this.
 solr.data.home if relative, will be set as SOLR_VAR_ROOT\{this}/solr.data.home
 solr.log.dir if relative, will be set as SOLR_VAR_ROOT\{this}/solr.log.dir

These references SOLR_VAR_ROOT\{this} isn't obvious.

> {{solr.data.home}} system property or {{solrDataHome}} in _solr.xml_ is already available as per SOLR-6671.
> The writable content in Solr are index files, core properties, and ZK data if embedded zookeeper is started in SolrCloud mode. It would be great if all writable content can come under the same directory to have separate READ-ONLY and WRITE-ONLY directories.
> It can then also solve official docker Solr image issues:
