我有这个简单的构建脚本:
import org.ajoberstar.grgit.Grgit
apply plugin: 'application'
apply plugin: 'org.ajoberstar.release-opinion'
task wrapper(type:Wrapper) {
gradleVersion = '2.1'
}
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'org.ajoberstar:gradle-git:0.11.+'
}
}
release {
grgit = Grgit.open(project.file('.'))
}
我创建了一个HelloWorld样式项目并初始化了git存储库.当我使用远程原点的目录时,我可以运行
.\gradlew.bat release
正好.但是当我使用ssh目标作为远程原点时,我得到以下输出:

我不想要这个sftpChannel.get("remotefile.txt","localfile.txt");
我只想创建两个方法1)将文件从远程位置复制到本地系统2)以删除sftp连接中复制的文件
谁能帮忙..
Java - Jsch sudo命令.
我正在使用Jsch,我的任务是登录服务器并运行命令,如下所示
sudo su - bumboo
使用以下代码我成功连接,但当我尝试运行命令时,它给了我错误 sudo: sorry, you must have a tty to run sudo
以下是我的代码
public static Channel sudoBamboo(Session session, String sudo_pass) throws Exception {
ChannelExec channel = (ChannelExec) session.openChannel("exec");
//SUDO to bamboo user
String command = "sudo su - bumboo";
channel.setCommand(command);
//InputStream in = channel.getInputStream();
channel.setInputStream(null, true);
OutputStream out = channel.getOutputStream();
//channel.setErrStream(System.err);
channel.setOutputStream(System.out, true);
channel.setExtOutputStream(System.err, true);
//Test change
//channel.setPty(false);
channel.connect();
out.write((sudo_pass + "\n").getBytes());
out.flush();
return channel;
}
他们建议使用sudo.java中的jsch
// man sudo
// -S …我正在尝试使用JSCH库版本0.1.49连接到SFTP远程服务器.每次运行程序时,都会收到以下错误:
Initializing...

第30行是:sftpChannel.connect()从下面的代码:
System.out.println("Initializing...");
JSch jsch = new JSch();
Session session = null;
try {
session = jsch.getSession(ProjectConstants.rmUsername,ProjectConstants.rmHost, 22);
session.setPassword(ProjectConstants.rmPassword);
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect();
if (session.isConnected() == true) {
System.out.println("Connection to SFTP server is successfully");
}
ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
try {
sftpChannel.connect();
} catch (Exception e) {
throw new …当下面的代码完成运行时,netstat -a|grep sftp显示一个打开的SFTP连接.它也显示为JProfiler中的开放连接.
channel.isConnected()在finally块中打印false.任何想法为什么连接没有被关闭,因为我不知所措？
public static void clean() {
com.jcraft.jsch.ChannelSftp channel = null;

DateTime fileDate = new DateTime(parseDateFromFileName(fileName));
//if this file is older than the cutoff date, delete from the SFTP share
if (fileDate.compareTo(cleanupCutoffdate) < 0) {
channel.rm(fileName);
}
}

我无法使用以下代码工作,我为此目的编写了这些代码.如果我在这里做任何蠢事,请告诉我.

我不想:
~/.ssh/known_hosts文件因此,StackExchange上的现有答案对我没有帮助,其中包括:
NullKnownHostProvider和设置hostKeyChecking为no.~/.ssh/known_hosts文件中输入的hostkey.这是我如何设想它可以在maven中设置的一个例子setup.xml:
<servers>
<server>
<id>gitcloud.myserver.net:8001</id>
<username>git</username>
<privateKey>C:/data/home/.ssh/id_rsa</privateKey>
<configuration>

<contents>codecloud.web.att.com ssh-rsa XXXXA3NvvFakeSSHKEYsdfADA...doLQ==</contents>
</knownHostsProvider>
</configuration>

</servers>
我下载了一个新的JSch 0.1.53库,并且JSch(sftp)下载任务不再有效.此版本在session.connect()函数抛出错误时失败Session.connect: java.io.IOException: End of IO Stream Read.
我的旧jsch.jar(2011-10-06)对同一主机工作正常,也许我错过了一个新的配置道具？
Session session=null;
ChannelSftp channel=null;
try {
JSch.setLogger(SSHUtil.createJschLogger());
JSch jsch=new JSch();
session=jsch.getSession("myuser", "11.22.33.44", 22);
session.setConfig("StrictHostKeyChecking", "no");
session.setPassword("mypwd");
session.connect(2000); // <-- FAILS HERE
channel = (ChannelSftp)session.openChannel("sftp");
channel.connect(2000);
