尝试运行Gradle Build时获取DisconnectableInputStream源阅读器 [英] Getting DisconnectableInputStream source reader while trying to run Gradle Build

问题描述

我有一个脚本，可以像这样运行 gradle build ...

I have a script that runs a gradle build like this...

$HOME_DIR$CODE_DIR/gradlew -p $HOME_DIR$CODE_DIR build

当我像 ./start.local.sh 这样定期运行此程序时，它可以正常工作.但是当我尝试像 nohup ./start.local.sh& 这样使用nohup时，我得到...

When I run this regularly like ./start.local.sh it works fine. But when I try to use nohup like nohup ./start.local.sh & I get...

Exception in thread "DisconnectableInputStream source reader" org.gradle.api.UncheckedIOException: java.io.IOException: Bad file descriptor
    at org.gradle.internal.UncheckedException.throwAsUncheckedException(UncheckedException.java:57)
    at org.gradle.internal.UncheckedException.throwAsUncheckedException(UncheckedException.java:40)

    at java.base/java.lang.Thread.run(Thread.java:844)
Caused by: java.io.IOException: Bad file descriptor

我想念什么?

推荐答案

尝试定义输入流描述符，这种魔术对我有效:

Try to define an input stream descriptor, this magic works for me:

nohup ./start.local.sh > build.log 2>&1 < /dev/null &

这是 https://issues.gradle.org/browse/中描述的已知Gradle错误.GRADLE-3535 .对输入(stdin)和输出流(stdout和stderr)的Gradle期望.使用nohup命令时，没有stdin和stdout/err，如果应用程序有严格的要求，则应定义它们:

This is a known Gradle bug described in https://issues.gradle.org/browse/GRADLE-3535. Gradle expect for input (stdin) and output streams(stdout and stderr). When you use nohup command there is no stdin and stdout/err and you should define them if application have a tight requirements:

 2>&1 - redirect for stderr to stdout, 
 > build.log - redirect stdout to log file, 
 < /dev/null - use /dev/null as input stream
