java我应该如何使用sshj来连接ssh，这让我很困惑

Question

虽然sshj的github中有一些例子，但我不明白自己在做什么。我使用以下代码尝试连接到我的主机，仅此而已

 @Test
    public void sshTest() throws IOException {
        SSHClient client = new SSHClient();
        String username = "username";
        File privateKey = new File("D:\\SSH\\remote_new");
        client.addHostKeyVerifier(new PromiscuousVerifier());
        client.connect("myMostIp", 22);
        KeyProvider keys = client.loadKeys(privateKey.getPath());
        client.authPublickey(username, keys);
        client.close();
    }

跑步的结果是这样的

net.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication methods


Caused by: net.schmizz.sshj.userauth.UserAuthException: Problem getting public key from PKCS8KeyFile{resource=[PrivateKeyFileResource] D:\SSH\matcloud_new}

    ... 66 more
Caused by: java.io.IOException: unrecognised object: OPENSSH PRIVATE KEY
    at org.bouncycastle.openssl.PEMParser.readObject(Unknown Source)
    ... 71 more

密钥文件的格式

-----BEGIN OPENSSH PRIVATE KEY-----
XXXXXXXXX
-----END OPENSSH PRIVATE KEY-----

我不知道该怎么办，jsch不支持这种格式的关键文件
