如何解决Travis CIs 4MB输出限制？

Question

我有一个Travis CI版本,可以产生超过4MB的输出,超过了Travis CI的限制.

我尝试将输出发送到/ dev/null,但如果10分钟内没有输出,Travis也会失败

我该如何解决这些限制？

Answer 1

以下脚本发送一些虚拟输出以使构建保持活动状态,但也会将构建输出记录到文件中,并在构建返回错误时显示输出的尾部:

#!/bin/bash
# Abort on Error
set -e

export PING_SLEEP=30s
export WORKDIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
export BUILD_OUTPUT=$WORKDIR/build.out

touch $BUILD_OUTPUT

dump_output() {
   echo Tailing the last 500 lines of output:
   tail -500 $BUILD_OUTPUT  
}
error_handler() {
  echo ERROR: An error was encountered with the build.
  dump_output
  exit 1
}
# If an error occurs, run our error handler to output a tail of the build
trap 'error_handler' ERR

# Set up a repeating loop to send some output to Travis.

bash -c "while true; do echo \$(date) - building ...; sleep $PING_SLEEP; done" &
PING_LOOP_PID=$!

# My build is using maven, but you could build anything with this, E.g.
# your_build_command_1 >> $BUILD_OUTPUT 2>&1
# your_build_command_2 >> $BUILD_OUTPUT 2>&1
mvn clean install >> $BUILD_OUTPUT 2>&1

# The build finished without returning an error so dump a tail of the output
dump_output

# nicely terminate the ping output loop
kill $PING_LOOP_PID

一个简单的替代方法是使用travis_wait命令。但是，这没有任何输出。
