How to get the Maven project name?

[wimdeblauwe]

inside of a ScanningRecipe, how do I get the Maven project name?

I have found that I can get the artifactId in the getScanner method like this:

@Override
  public TreeVisitor<?, ExecutionContext> getScanner(Accumulator acc) {
    return new TreeVisitor<>() {
      @Override
      public @Nullable Tree visit(@Nullable Tree tree, ExecutionContext ctx) {
        if (!(tree instanceof SourceFile)) {
          return tree;
        }
        SourceFile sourceFile = (SourceFile) tree;
        String sourcePath = PathUtils.separatorsToUnix(sourceFile.getSourcePath().toString());

        if (sourcePath.equals("pom.xml") && tree instanceof Xml.Document) {
          extractInformationFromPom(tree, ctx);
        }

        return tree;
      }

      private void extractInformationFromPom(Tree tree, ExecutionContext ctx) {
        new MavenIsoVisitor<ExecutionContext>() {
          @Override
          public Document visitDocument(Document document, ExecutionContext ctx) {
            document
                .getMarkers()
                .findFirst(MavenResolutionResult.class)
                .ifPresent(maven -> acc.artifactId = maven.getPom().getArtifactId());
            return document;
          }
        }.visit(tree, ctx);
      }
    };
  }

But there seems to be no method to get the Maven project name on maven or on maven.getPom() ?

The RawPom has a name field that sounds like what you're after, but it's hard to be sure from the above. Does that work for you?

rewrite/rewrite-maven/src/main/java/org/openrewrite/maven/internal/RawPom.java

Lines 88 to 89 in 66585e1

	@Nullable
	String name;

I am looking for the content of the <name> element in the pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    ...
  </parent>
  <groupId>com.example</groupId>
  <artifactId>demo</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>demo</name> <!-- This is what I need -->
  ..

How could I access RawPom ?

MavenResolutionResult has a field ResolvedPom pom, which has a field Pom requested, which as a field String name which I think is what you're after.

That does work indeed, thanks!
