RE: Properties/Variables in pom?
Hi,
Are the default properties documented at all somewhere?

Re: Properties/Variables in pom?
Posted by Jesse McConnell <je...@gmail.com>.
I'll explain a bit more...
you see how the pom.xml is laid out, right?
<project>
<build>
<outputDirectory>{$basedir}target/classes</outputDirectory>
<testOutputDirectory>${basedir}target/test-classes</testOutputDirectory>
</build>
</project>
there is a super-pom which is the parent of all the pom.xml that users
create, in that super pom a mess of these things are defined as the defaults
for the project, where the build output would go, where the test classes
will go, etc.
you can refer to a lot of these things like ${project.build.outputDirectory}
in expressions in your poms and those are ironed out when the private
variables are being injected.
I don't know if there is a full listing of what these all are, but that is
the 'how' and 'why' they exist
if you want to know more, just ask

Most of your pom's element can be referenced as ${project.x.y....},
so ${project.build.directory} by default is path_to_your "target" dir.

Hi!
AFAIK, this only works _within_ the POM itself (i.e. in the
configuration section of plugins). I don´t know if it works for the
file-filtering stuff.

Has anyone actually been able to get this working? All of the filtering
works fine for me, but the environment variable stuff does not. As a test I
have a properties file that contains:
${env.JAVA_HOME}
${user.home}
${pom.version}
After the process-resources phase (with filtering turn on in the pom), the
file looks like this:
${env.JAVA_HOME}
/home/build
1.2-SNAPSHOT
JAVA_HOME is definitely set, is there something I am doing wrong, or does
this just not work?

Gareth
Hi Andreas!
Take a look at the Getting Started Guide
(http://maven.apache.org/guides/getting-started/index.html), section
"How do I filter resource files?". It explains how to reference the
elements of the pom.xml/settings.xml using property-names.
I´m currently working on a book that covers Maven 2 as part of a
pragmatic configuration management process and have done some "research"
concerning the usage of properties. AFAIK, properties are resolved in
the following order:
- The (hard-coded) property ${basedir} (contains the path of the POM-file)
- All Java System Properties defined by the JVM.
- All properties defined in the properties-element of the POM.
- All elements in pom.xml and settings.xml as stated above
- All (platform-specific) Environment variables (Just add the prefix
env. For example ${env.M2_HOME} returns the Maven2 installation path).
I´m not 100% sure about the list and appreciate any additions/corrections.
CU,
Gunther

I've already read that section before, but I don't consider these two sentences explaining:
First, it's mentioned at the wrong place (when I'm looking for available properties, I would go the the POM references, I think. But not where I filter resource files.
Second:
"To accomplish this in Maven, put a reference to the property that will contain the value into your resource file using the syntax ${<property name>}. The property can be one of the values defined in your pom.xml, a value defined in the user's settings.xml, a property defined in an external properties file, or a system property."
Leaves a couple of questions:
* What's the syntax of <property name>? Apparently some dot-separated grammar.
* Does that apply to all elements in the POM? If yes, how are multiple children with the same name addressed?

Sorry, I don't understand, what you're trying to tell me :-) Can you please add one or two sentences :-) Is ${project.build.directory} one variable or can I somehow look the others up by using that?
