要确定Artifactory的maven仓库是否被禁用，可以使用以下代码示例：

import org.apache.maven.repository.internal.MavenRepositorySystemUtils;
import org.eclipse.aether.RepositorySystem;
import org.eclipse.aether.repository.RemoteRepository;
import org.eclipse.aether.repository.RepositoryPolicy;
import org.eclipse.aether.resolution.ArtifactResolutionException;
import org.eclipse.aether.resolution.ArtifactResult;
import org.eclipse.aether.resolution.DependencyRequest;
import org.eclipse.aether.resolution.DependencyResolutionException;
import org.eclipse.aether.resolution.DependencyResult;
import org.eclipse.aether.resolution.VersionRangeRequest;
import org.eclipse.aether.resolution.VersionRangeResult;
import org.eclipse.aether.version.Version;

public class ArtifactoryMavenRepositoryCheck {
    public static void main(String[] args) {
        // Artifactory Maven仓库的URL
        String repositoryUrl = "https://example.com/artifactory/maven";
        
        // 创建RepositorySystem对象
        RepositorySystem repositorySystem = MavenRepositorySystemUtils.newServiceLocator().getService(RepositorySystem.class);
        
        // 创建RemoteRepository对象
        RemoteRepository repository = new RemoteRepository.Builder("artifactory", "default", repositoryUrl)
                .setSnapshotPolicy(new RepositoryPolicy(true, RepositoryPolicy.UPDATE_POLICY_NEVER, RepositoryPolicy.CHECKSUM_POLICY_WARN))
                .setReleasePolicy(new RepositoryPolicy(true, RepositoryPolicy.UPDATE_POLICY_NEVER, RepositoryPolicy.CHECKSUM_POLICY_WARN))
                .build();
        
        // 创建VersionRangeRequest对象
        VersionRangeRequest versionRangeRequest = new VersionRangeRequest();
        versionRangeRequest.setArtifact(ArtifactDescriptorRequest.createArtifact("com.example", "example-artifact", "1.0.0", "jar"));
        versionRangeRequest.setRepositories(Collections.singletonList(repository));
        
        try {
            // 获取版本范围结果
            VersionRangeResult versionRangeResult = repositorySystem.resolveVersionRange(session, versionRangeRequest);
            
            // 获取最新版本
            Version latestVersion = versionRangeResult.getHighestVersion();
            
            // 输出最新版本
            System.out.println("Latest version: " + latestVersion);
        } catch (ArtifactResolutionException e) {
            // 处理异常
            e.printStackTrace();
        }
    }
}

这段代码使用Eclipse Aether库来解析Artifactory的maven仓库中的元数据，并获取最新的版本号。如果代码能够成功执行并打印出最新的版本号，那么说明Artifactory的maven仓库是可用的。如果代码抛出ArtifactResolutionException异常或打印出错误信息，则说明Artifactory的maven仓库可能被禁用或无法访问。
