新しいRestS3Serviceは例外をスローしないため、正常に接続できるようです。

ただし、 getBucket（ "name"）のようなことをしようとすると、次のようになります。無効なクラス名：org.jets3t.service.utils.RestUtils $ ConnManagerFactory

これを解決する方法はありますか？

ありがとう！

私のコード：

    AWSCredentials awsCredentials = new AWSCredentials(awsAccessKey, awsSecretKey);
    S3Service s3Service = null;

    System.out.println("Credentials created, trying Service");

    try {
        s3Service = new RestS3Service(awsCredentials);
    } catch (S3ServiceException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    System.out.println("Service connected, trying bucket grab");

    try {
        S3Bucket bucket = s3Service.getBucket("mrbucket");
        System.out.println("bucket grabbed: "+bucket.getName());
    } catch (S3ServiceException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

出力：

Credentials created, trying Service

Installer - Installer service created

Service connected, trying bucket grab

org.jets3t.service.utils.RestUtils$ConnManagerFactory.classがクラスパスにないようです。JetS3tライブラリ全体を利用できますか？ライブラリには約19個のjarがあり、RestUtils$ConnManagerFactory.classは0.8.1aバージョンのjet3t-0.8.1a.jarにあります。

Groovyユーザー：この例外は、 Grapeを使用したGroovyスクリプトでjets3tを依存関係として宣言している場合にもスローされます。

この場合は、システムクラスローダーを使用するようにGrapeを構成する必要があります。

@GrabConfig(systemClassLoader=true)
@Grab(group='net.java.dev.jets3t', module='jets3t', version='0.9.4')
