Bitbucket Pipelines - “无法识别术语'chmod*'”错误

问：

我是 Bitbucket 中管道的初学者。我有一个项目，其中包含一个 .ymal 文件，我需要将其推送到 bitbucket，这将触发管道。但是，触发的管道将无法成功完成，并生成以下错误消息：

+ chmod - R +× $BITBUCKET_ CLONE DIR/*
Invoke-Expression: The term 'chmod* is not recognized as the name of a cmdlet, function, script file, or operal program. Check the spelling of the name, or if a path was included, verify that the path is correct and try aga.
At C: \…….. char: 40
"chmod -R +x $BITBUCKET_CLONE_DIR/** | Invoke-Expression
+
+ CategoryInfo
ObjectNotFound: (chmod:String) [Invoke-Expression], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException, Microsoft.PowerShell.Commands . InvokeExpressionCommand

有人可以向我解释什么是错误以及如何解决这个问题吗？

这是我的.ymal文件：

definitions:
    steps:
        step: &run_on_self_hosted_runner
            runs-on:
                - self.hosted
                - windows
                - savalktest

        script:
                        - chmod -R + $BITBUCKET CLONE DIR/*
                        - $BITBUCKET_CLONE_DIR/DA/bitbucketscript/project-init.sh

                        #- px cypress run --browser chrome
                        #- sleep 600
        after-script:
                        echo "Exit status is :$BITBUCKET EXIT CODE"
                        - if [[$BITBUCKET_EXIT_CODE=-0]] ;then BUILD_ STATUS-"Pass"; exit 0;
        artifacts:
            - DA/reports/**
            - DA/cypress/videos/**
            - DA/cypress/screenshots/**

非常感谢任何解决此问题的帮助...... :D
