我有一个.properties文件,其中包含以下属性:
repository.host=hostname.com/nexus
repository.api.url=https://${repository.host}/service/rest/v1
repository.url=https://${repository.host}/repository我能够使用以下powershell函数返回值:
static [string] getProperty( [string] $property ){
$properties = "../resources/vars/$([jenkins]::PROPERTIES_FILE)"
$properties = get-content $properties | convertfrom-stringdata
return $properties.$property
}当尝试返回属性repository.url powershell时,返回以下字符串:https://${repository.host}/repository/
我的问题是:是否可以通过powershell中已经存在的特性将返回的字符串设置为https://hostname.com/nexus/repository/

@mclement0提供的原始解决方案非常有用,并指导我找到了一个更完整的解决方案。这个解决方案完成/纠正了以下几件事情:
$ExecutionContext作用域从类方法中访问$global:变量的能力。 static [string] getProperties ( [string] $file, [string] $property ){
$properties = get-content $file -raw | convertfrom-stringdata
while ( $properties.values -match '\$\{([^}]+)\}' ){
foreach ($key in @($properties.Keys)) {
$properties[$key] = $global:ExecutionContext.InvokeCommand.ExpandString( ($properties[$key] -replace '\$\{([^}]+)\}', '$$($$properties[''$1''])') )
}
}
return $properties[$property]
}注意:当while循环不存在并且搜索${*}的匹配项时,任何给定的返回值都不可能被完全内插或展开。例如,如果没有while循环,文件的输出可能如下所示:
/nexus
${nexus.protocol}://${nexus.hostname}:${nexus.port}${nexus.context}
${nexus.protocol}://${nexus.hostname}:${nexus.port}${nexus.context}/repository/installers/com/amazon/java/8.0.252/java-1.8.0-amazon-corretto-devel-1.8.0_252.b09-1.x86_64.rpm
