Ivy (Ant) support

Detect includes two Ivy detectors:

• Ivy CLI Detector

• Ivy Build Parse Detector

• Detector for Ant + Ivy projects, extracts direct and transitive dependencies using the ivy:dependencytree Ant task.

Requirements:

• A valid ant executable must be available on the system.

• An ivy.xml and build.xml file must be present in the project.

• build.xml must contain a target with the <ivy:dependencytree> task.

• Apache Ant 1.6.0+ and Apache Ivy 2.4.0+ required.

Behavior:

• Automatically discovers the target containing <ivy:dependencytree> in build.xml.

• Executes ant <targetName> to generate the dependency tree.

• Parses the output to construct a hierarchical dependency graph with parent-child relationships.

• Falls back to the Ivy Build Parse Detector if ivy:dependencytree is unavailable.

To specify a custom Ant executable path, use the detect.ant.path property.

To facilitate dependency tree generation, the build.xml must contain a target with the ivy:dependencytree task:

<target name="dependencytree">
    <ivy:resolve />
    <ivy:dependencytree log="download-only" />
</target>

If ivy:dependencytree is unavailable, Detect will default to the Ivy Build Parse Detector, which extracts dependencies by parsing the ivy.xml file.

• Parses ivy.xml for direct dependency declarations only. Transitive dependencies are not resolved.

• Extracts the project name and version from build.xml. If the project name or version is missing, the values are derived via Git from the project's directory or defaults.
