azure - failOnStderr: true 时的 Azure 脚本任务，出现非没有此标志的 bash 错误

Question

当failOnStderr：true未在任务中设置时，我有有线行为一切正常但是
当我使用failOnStderr调用这样的脚本任务时：true：

- script:  |
     echo 'Start invoking Fastfile'
     fastlane release --verbose projectName:${{parameters.projectName}} appIdentifier:${{parameters.appIdentifier}} versionNumber:${{parameters.versionNumber}} buildNumber:${{parameters.buildNumber}} plistFileFtpBasePath:${{parameters.plistFileFtpBasePath}} ArtifactsDirectory:$(System.ArtifactsDirectory)
     echo 'Done invoking Fastfile'
    failOnStderr: true 
    workingDirectory: '$(System.ArtifactsDirectory)/ios_artifacts'
    displayName: 'create keychain invoke fastlane'

我收到此错误：

设置为 false 时更新 仍然不起作用

- script:  |
     echo 'Start invoking Fastfile'
     fastlane release --verbose projectName:${{parameters.projectName}} appIdentifier:${{parameters.appIdentifier}} versionNumber:${{parameters.versionNumber}} buildNumber:${{parameters.buildNumber}} plistFileFtpBasePath:${{parameters.plistFileFtpBasePath}} ArtifactsDirectory:$(System.ArtifactsDirectory)
     echo 'Done invoking Fastfile'
    failOnStderr: false
    workingDirectory: '$(System.ArtifactsDirectory)/ios_artifacts'
    displayName: 'create keychain invoke fastlane'

Answer 1

这是预期的行为。

设置后，如果将任何错误写入StandardError流，failOnStderr: true则任务将失败。

相反，如果failOnStderr是false，任务的失败将取决于退出代码。退出代码不为0时，任务将失败。

正常情况下，您应该知道将错误写入stderr不会导致退出代码为非零。failOnStderr是true或是false两种不同的失效条件。

根据您分享的日志：

2020-09-30T07:54:45.9020160Z ##[error]Bash wrote one or more lines to the standard error stream.

您可以看到有一些错误写入Stderr流。此时，由于您设置failOnStderr为，任务按预期失败true。
