Re: Newbie question on MOJOs
Hi Ritu, I'm not sure what your goal is, but if you're just trying to do a simple compilation of source code, you might want to simply point your POM at the source directory, and try calling `mvn compile`. By default, Maven will compile the source files for you...it's part of the default lifecycle for jar projects. POM syntax for source directory: [...] relative/source/dir HTH, john On 8/14/06, franz see <[EMAIL PROTECTED]> wrote: Good day to you, Ritu > Hi, > > I am new to Maven2.

Re: Ad: Newbie question on MOJOs
Hi Stefan,
Thanks for that quick response.
I took a look at the compiler plugin. It uses quite a lot of current build
context references, for e.g. project.compileClasspathElements.
Would you know if there is any single source of document on all the
available Maven2 properties/references? In Maven 1.x there was a reference
page available for all the default Maven properties. I didn't find similar
documentation in Maven2. Any pointers will be very much appreciated.
Thanks again,
Ritu

Hi there,
Have a look at the maven-compiler-plugin plugin. It should provide you

Newbie question on MOJOs
Hi, I am new to Maven2. I am trying to develop plugins in Maven2 using the Java Plugins approach. I have seen the getting started guide on MOJOs (http://maven.apache.org/guides/plugin/guide-java-plugin-development.html). But this is too elementary. Could someone please point me to some more advanced guide to building MOJOs, one which contains integration with Ant Java APIs? I have taken a look at the AntExternal guide as well: http://ant.apache.org/manual/antexternal.html. At this point, I am simply trying to use Ant's Javac.java API to compile my source code using a MOJO. I had the following questiions: 1. How do I get access to maven's dependency classpath (i.e. path containing all the dependencies defined in project's pom.xml)? In Maven 1.x this was accessible using maven.dependency.classpath reference in plugin.jelly. 2. How does Maven set the java.home System Property? I have set the environment var "Java_Home" to the jdk directory but Maven is setting the java.home System property to the jre directory (i.e. /jre). Why is that so? Has anyone used Ant's Javac API to do the compilation from inside a MOJO. If yes, could you please send me the code snippet to set the classpath and any other system properties?
