Re: [FMPP] FMPP SourceFile Classpath

[Shelley, R. <Rya...@di...>]

Well, what I really need is to be able to put my template and sources in
a JAR, and then in my .fmpp config files, reference them like:

sources: classpath:/in/my/classpath/source.properties
inheritConfiguration: classpath:/in/my/classpath/template.properties

or in the Ant Task, like:

<fmpp sourceFile="classpath:/in/my/classpath/template.properties"
data="classpath:/in/my/classpath/data.properties" />
    Or
<fmpp configuration="classpath:/in/my/classpath/foobar.fmpp"
data="classpath:/in/my/classpath/data.properties" />

Then I can bundle my sources and templates in a JAR that can be read
when that JAR is loaded on the classpath, then run my Maven Ant Tasks
and have those resources found without having to give explicit
filesystem paths.

Here's the scenario. I have two maven projects, one that builds a JAR
that contains resource files and some classes (say, an arbitrary Service
module), the second (say, a WAR Web App) depends on the first (the web
component uses the arbitrary Service module) and has a Maven Ant Run
FMPP task to generate some property files based upon the templates that
exist in the first project that configures the dependent Service for
that specific Web app.  At the moment, my FMPP Ant Task takes a
filesystem path to the configuration file or the filesystem path to the
source and data files.

Right now my Maven Ant Tasks, configuration files, etc all need
relative/absolute filesystem paths that may change between developer
environments (our source repo allows arbitrary folder mapping in
workspaces, so I can't guarantee another developer's project workspace
looks like mine).

If it's not currently supported, that's fine, just want make sure I'm
not missing some functionality that's built in.  And if not, maybe
(assuming I get some bandwidth), I could help contribute.  Thanks!

Which is not at all trivial to do for those who are not wrestled in
Java... so, here is the recipe:

(a) Easy but dirty solution: Just drop the jar into $FMPP_HOME/lib,
and it will automatically see it, but only when you are using the
$FMPP_HOME/bin/fmpp shell script for running the FMPP projects. This
has global effect in the sense that all FMPP projects that are run
with $FMPP_HOME/bin/fmpp will see the extra jars added there.

(b) The clean solution: Create a "lib" sub-directory in your FMPP
*project* directory, and drop the extra jar into there. Then, in the
same directory you should create a bash script (or .bat, on Windows)
that runs FMPP with your own custom class-path:

  On Linux/UN*X:

    java -cp
./lib/yourExtra1.jar:./lib/yourExtra2.jar:$FMPP_HOME/lib/fmpp.jar
fmpp.tools.CommandLine

  On Windows:

    java -cp
.\lib\yourExtra1.jar;.\lib\yourExtra2.jar;%FMPP_HOME%\lib\fmpp.jar
fmpp.tools.CommandLine

Note that the scrip assumes that the working directory is already your
project directory (you may need to "cd" into it as the first step in
the script). Also it assumes that you have an FMPP_HOME environment
variable; if you don't have it, not a problem, just replace it with a
concrete path in the above scripts (or better, define the environment
variable locally in the scrip).

Yeah, someday I should invest into writing a native launcher app. that
does all the Java setup magic automatically... /-:
