Support to search about pom dependency #170
Description
Proposition
The project currently supports to search about java symbols: import, annotation, class, method, field and could be also extended to support to search about pom dependency, plugin, properties, etc
The main benefit to include such a search capability part of this project will be that the query language of the Rule could be simplified for the user to avoid to use XPath queries and buildin parser
when:
condition: pom.dependency is (gav='g:a:v,g:a:v,g:a:v,...')
condition: pom.dependency is (groupId='g', artifactIr='a', version='v')
and to leverage too from the language server to perform queries the analyzing phase.
The development of such queries are not too complex as we could use from the pom.xml loaded by the server
DefaultModelBuildingRequest req = new DefaultModelBuildingRequest();
req.setProcessPlugins(false);
req.setPomFile(new File(pomPath));
req.setValidationLevel(ModelBuildingRequest.VALIDATION_LEVEL_MINIMAL);
req.setSystemProperties(System.getProperties());
req.setModelResolver(new RepositoryModelResolver());
ModelBuildingResult result;
try {
result = modelBuilder.build(req);
} catch (Exception e) {
System.out.println("Could not build effective model: " + e.getMessage());
return Optional.empty();
}
// Then we can iterate and search over the model
Model model = result.getEffectiveModel();
public Optional searchDependency(Model model, String groupId, String artifactId, String version) {
if (model.getDependencyManagement() != null) {
Optional<Dependency> dep = model.getDependencyManagement().getDependencies().stream()
.filter(d -> groupId.equals(d.getGroupId()) && artifactId.equals(d.getArtifactId()))
.findFirst();
if (dep.isPresent()) {
// !!! Location is empty
return Optional.ofNullable(dep.get().getLocation(""));
}
}
if (model.getDependencies() != null) {
Optional<Dependency> dep = model.getDependencies().stream()
.filter(d -> groupId.equals(d.getGroupId()) && artifactId.equals(d.getArtifactId()))
.findFirst();
if (dep.isPresent()) {
// Found it!
return Optional.ofNullable(dep.get().getLocation(""));
}
}
return Optional.empty();
