Eric Pugh commented on SOLR-17746:
----------------------------------
Did some digging... I am putting up a PR that first cleans some docs up about
--jettyconfig, and then adds a test. Can you look at it?
I asked GPT about what the "${2:0:1}" == "-" ] is about, and basically it
ensures that you don't forget to provide a value for the option, like in this
example for port: --port --jettyconfig blah.
However, there is no real pattern for that check and I can see that removing it
globaly might make sense?
> bin/solr always fails if you attempt to use --jettyconfig (aka "-j")

> Key: SOLR-17746
> URL: https://issues.apache.org/jira/browse/SOLR-17746
> Project: Solr
> Issue Type: Bug
> Reporter: Chris M. Hostetter
> Priority: Major
>
> The "-jettyconfig" optiona (aka "-j") is documented as...
> {noformat}
> -j <jettyParams> Additional parameters to pass to Jetty when starting
> Solr.
> For example, to add configuration folder that jetty
> should read
> you could pass: -j
> "--include-jetty-dir=/etc/jetty/custom/server/"
> In most cases, you should wrap the additional
> parameters in double quotes.
> {noformat}
> ..but if you actually attempt to run use that example option, you will get
> an error...
> {noformat}
> ./bin/solr start ... -j "--include-jetty-dir=/etc/jetty/custom/server/"
> ERROR: Jetty config is required when using the -j option!
> {noformat}
> IIUC this is because the bash code for parsing this option requires that it
> not start with a "{{\-}}" character; but by definition any option you want to
> pass to jetty will start with "{{\--}}".
> Attempting to workaround this problem by using two sets of quotes doesn't
> seem to work -- the inner quotes are passed verbatim to jetty which seems to
> prevent jetty from recognizing it as a valid option.
> A workaround that *does* seem to work (in my limited testing) is to include a
> leading space character _inside_ the quotes...
> {noformat}
> ./bin/solr start ... -j " --include-jetty-dir=/etc/jetty/custom/server/"
> {noformat}
> ...because for some reason that does *NOT* seem to be passed verbatim.
