I'm trying to add the ability to read a pom.xml file within a Grails application. So I have logic like this:
if (readPom) {
def pomFile = new File(basedir, "pom.xml")
final modelRequest = new DefaultModelBuildingRequest()
modelRequest.setPomFile(pomFile)
ModelBuildingResult modelBuildingResult = modelBuilder.build(modelRequest)
final mavenDependencies = modelBuildingResult.getRawModel().getDependencies()
for (org.apache.maven.model.Dependency md in mavenDependencies) {
final dependency = new Dependency(new DefaultArtifact(md.groupId, md.artifactId, md.classifier, md.type, md.version), md.scope)
addDependency(dependency)
}
}
Which reads the POM and converters the Maven dependencies into Aether's model. The problem I'm running in to is that properties are not correctly evaluated. The pom.xml file defines a property like:
<properties>
<grails.version>2.3.0.BUILD-SNAPSHOT</grails.version>
</properties>
Which is later used in the dependency definitions:
<dependency>
<groupId>org.grails</groupId>
<artifactId>grails-dependencies</artifactId>
<version>${grails.version}</version>
<type>pom</type>
</dependency>
This works fine when using the 'mvn' command but when using 'grails' and hence the code originally posted above. I get the following exception:
at java.net.URI$Parser.fail(URI.java:2810)
at java.net.URI$Parser.checkChars(URI.java:2983)
The properties don't appear to be being substituted.
Is there a correct way to convert the Maven model into the Aether model that deals with this issue?
Thanks again
