我正在使用 java 来运行 shell 脚本，它运行得很好。现在我想从此脚本中获取错误，例如我有一个脚本，并且有一个错误，我想获取该错误的行和消息
这是我运行 shell 脚本的代码。
try {
JSch jsch=new JSch();
com.jcraft.jsch.Session session=jsch.getSession(jTextField1.getText() ,jTextField3.getText(),22);
session.setPassword(jTextField2.getText());
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect();
ChannelExec channel=(ChannelExec) session.openChannel("exec");
channel.setInputStream(System.in);
channel.setOutputStream(System.out);
/*cp .mbb.sh to /
chmod +x mbb.sh
./mbb.sh param1 param2*/
//chaine de caractére pour concatener les parametres
String param="";
for ( int j=0 ; j<list.size();j++){
param=param+" "+list.get(j).getText();
}
DB_Operation db = new DB_Operation();
db.getConnection();
channel.setCommand("bash"+" "+valeururl+ param);
//channel.setCommand("bash script.sh");
channel.connect(30000);
InputStream in = channel.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
String line ;
result.add("Build successful \n");
while((line =reader.readLine())!=null){
result.add(line);
}
if ( session.isConnected()){
JOptionPane.showMessageDialog(rootPane, "Connecté");
Resultexec rs =new Resultexec(result);
xx.dispose();
rs.createAndShowGUI();
}
} catch (JSchException ex) {
result.clear();
result.add("Build failed \n");
msg_console = ex.getMessage();
result.add(msg_console);
JOptionPane.showMessageDialog(rootPane, "Erreur de connexion ");
Resultexec rs =new Resultexec(result);
xx.dispose();
rs.createAndShowGUI();
} catch (IOException ex) {
result.clear();
result.add("Build failed \n");
msg_console = ex.getMessage();
result.add(msg_console);
Resultexec rs =new Resultexec(result);
xx.dispose();
rs.createAndShowGUI();
}
答案1
你好，我对代码做了一些修改，它可以工作
