Gradle Exec任务不退出 [英] Gradle Exec task not exiting

问题描述

我的gradle任务：

  task startTomcat（type：Exec）{
 workingDir ENV ['CATALINA_HOME'] +'/ bin'
 commandLine'cmd'，' / c'，'catalina.bat'
 args'start'
} 
  

当我运行这个任务时，tomcat确实启动。但是这项任务并没有完成，并且一直在等待。
我已经通过执行文档页面，但无法得到任何线索。

请帮助。

解决方案

感谢Peter的意见。下面是使用 ProcessBuilder 为我工作的解决方案：

  / * tomcat的配置* / 
任务catalinaConfig {
 ext.binDir = ENV ['CATALINA_HOME'] +\\bin
} 
 
任务startTomcat< ;< {
 printlnTomcat path：+ catalinaConfig.binDir 
 ProcessBuilder pb = new ProcessBuilder（[cmd，/ c，catalina.bat，start]）; 
 pb.directory（新文件（catalinaConfig.binDir））; 
 
 println现在启动tomcat ...
 Process proc = pb.start（）; 
 proc.waitFor（）; 
 printlnTomcat即将上架......+ proc.exitValue（）
} 
 
任务stopTomcat<< {
 printlnTomcat path：+ catalinaConfig.binDir 
 ProcessBuilder pb1 = new ProcessBuilder（[cmd，/ c，catalina.bat，stop]）; 
 pb1.directory（new File（catalinaConfig.binDir））; 
 
 println现在停止tomcat ...
进程proc1 = pb1.start（）; 
 proc1.waitFor（）; 
} 
  

I am new to Gradle and I am using a small task to start/stop local tomcat server.

My gradle task:

task startTomcat(type: Exec){
    workingDir ENV['CATALINA_HOME'] + '/bin'
    commandLine 'cmd', '/c', 'catalina.bat'
    args 'start'
}

When I run this task, tomcat does start. But the task is not completing and keeps on waiting. I have gone through Exec documentation page but could not get any clue.

Please help.

解决方案

Thanks Peter for the input. Here is the solution that worked for me using ProcessBuilder:

/* Configuration for tomcat */
task catalinaConfig {
    ext.binDir = ENV['CATALINA_HOME'] + "\\bin"
}

task startTomcat << {   
    println "Tomcat path: " + catalinaConfig.binDir 
    ProcessBuilder pb = new ProcessBuilder(["cmd", "/c", "catalina.bat", "start"]);
    pb.directory(new File(catalinaConfig.binDir));

    println "Starting tomcat now ... "
    Process proc = pb.start();
    proc.waitFor();
    println "Tomcat is coming up now ... " + proc.exitValue()
}

task stopTomcat << {    
    println "Tomcat path: " + catalinaConfig.binDir 
    ProcessBuilder pb1 = new ProcessBuilder(["cmd", "/c", "catalina.bat", "stop"]);
    pb1.directory(new File(catalinaConfig.binDir));

    println "Stopping tomcat now ... "
    Process proc1 = pb1.start();
    proc1.waitFor();
}
