Task startServer Hangs

[kirankbs]

Build is hanging at startServer.
It is not going ahead to execute remaining tasks.

build.gradle:-

apply plugin: 'com.wiredforcode.spawn'

task startServer(type: SpawnProcessTask, dependsOn: 'assemble') {
command "startApplication.bat"
ready 'Started.Application'
pidLockFileName ".new.pid.lock"
}

task stopServer(type: KillProcessTask)

---

cmd Output:-

gradle clean startS stopS

@georgepapas and @brookslyrette - I'm facing the same issue. Did you find any solution for it? thanks

I had the same issue and I think I found out why it is happening. The "ready" directive means it is waiting for the string that you pass to it to appear on standard out. So you will have to specify something your "startApplication.bat" is printing on standard out when it is finished starting. For example, if you have a program which prints "I am a server, I run now on port 8080", you will have to use
ready 'I am a server, I run now on port 8080'
in the task. You can also just use
ready 'I am a server, I run now on port'
since it will do a "contains".

At leas that was what I did wrong and once I fixed it the plugin worked like a charm.

Here is the relevant code from the plugin itself:

    private boolean waitUntilIsReadyOrEnd(Process process) {
        def line
        def reader = new BufferedReader(new InputStreamReader(process.getInputStream()))
        boolean isReady = false
        while (!isReady && (line = reader.readLine()) != null) {
            logger.quiet line
            runOutputActions(line)
            if (line.contains(ready)) {
                logger.quiet "$command is ready."
                isReady = true
            }
        }
        isReady
    }

I also have a similar issue. When using 0.6.0 my tests continue after Spring Boot has started. Using 0.8.0, it just hangs for some amount of time between 2 and 8 minutes, then will continue. No changes other than the version.
