Provide version-independent command(s) to start launchpad?
Hi Sling devs,
according to the website the following command has to be used to start
the launchpad:
java -jar
target/org.apache.sling.launchpad.app-2.0.0-incubator-SNAPSHOT.jar -c
sling -f -
Since it includes the version number, one has to change the command to
fit the current version, or you'd have to update the website continuously.
Would it make sense to provide version-independent commands, e.g.
sling.sh and sling.bat? Or maybe it's possible to use Maven for this
purpose (I'm not familiar yet with the Maven capabilities)?

Thanks for the pointer!
Do you mean something like this?
Index: launchpad/app/pom.xml
===================================================================
--- launchpad/app/pom.xml (revision 738488)

This seems to work for me.

We could use the finalName configuration (for the app and the webapp),
this ensures that the artifact in the target dir has always the same
name - this doesn't affect the name in the repo.
WDYT?

Maven has some support (plugin) to generate the start scripts with
everything one needs.
Archiva and Continuum are using this for instance.
I can't remember out of my head how, but I'll look it up.

I agree with respect to webapps -- webapps are to be deployed into
whatever container is available.
With respect to the standalone Jar, I think it would be nice to have a
set of very simple scripts to launch sling. With "simple" I mean the
kind thing:
#!/bin/sh
JAVA_HOME=... find it out ...
${JAVA_HOME}/bin/java -jar path/to/sling.jar $@
or slightly more elaborate to also enable debugging by a simple command
line argument.
But for the short term, I agree, the scripts should be removed.

Felix

The launchpad/app jar is executable, you don't need ant to run it.

Yeah. I've frequently argued that an Ant script is almost always the
right way to run Java cross-platform. Not only does it have some of the
best launch scripts (it will figure out JAVA_HOME in most any
situation), but Ant is frequently already installed (like on Mac) or
just an apt-get or rpm away.
Of course an executable JAR is even better if it suits the application.

I suggest removing those scripts - there are much better utilities
around to start runnable jars or webapps, I think that's outside of
Sling's scope.

IIRC these are meant to be copied (and filtered) by the assembly profile
when build app.
On a similar recount: I think, these scripts would need some work, in
other works made simpler. Esp. the unix shell script is much too
complicated IMHO.

I just noticed that there are server control commands in
launchpad/app/src/main/dist/windows and …/unix. Are they meant for the
purpose I mentioned? Unfortunately the unix commands don't work on the Mac:
…/launchpad/app/src/main/dist/unix/serverctl: line 313:
$SLING_CONTEXT/bin/${project.build.finalName}.jar: bad substitution
…/launchpad/app/src/main/dist/unix/serverctl: line 410: $SLING_JVM
$jvmOpts -jar $SLING_CONTEXT/bin/${project.build.finalName}.jar
$slingOpts: bad substitution
