DependsOnTargets
和 AfterTargets
有什么区别?
我无法区分这两个。
最佳答案
取决于目标
定义目标 必须在 目标可以执行之前执行。
<Target Name="DependsOn" DependsOnTargets="DependencyTarget1;DependencyTarget2">
<Message Text="Target : DependsOn"/>
</Target>
<Target Name="DependencyTarget2">
<Message Text="Target : DependencyTarget2"/>
</Target>
<Target Name="DependencyTarget1">
<Message Text="Target : DependencyTarget1"/>
</Target>
Output
> Target : DependencyTarget1
> Target : DependencyTarget2
> Target : DependsOn
BeforeTargets 和 AfterTargets(仅在 MSBuild 4 中可用)
指示目标应该在 之前或之后运行 指定的一个或多个目标。
<Target Name="BeforeAndAfter">
<Message Text="Target : BeforeAndAfter"/>
</Target>
<!-- BeforeTarget1 will run BEFORE target "BeforeAndAfter" -->
<Target Name="BeforeTarget" BeforeTargets="BeforeAndAfter">
<Message Text="BeforeTarget run before : BeforeAndAfter"/>
</Target>
<!-- BeforeTarget1 will run AFTER target "BeforeAndAfter" -->
<Target Name="AfterTarget" AfterTargets="BeforeAndAfter">
<Message Text="AfterTarget run after : BeforeAndAfter"/>
</Target>
Output
> BeforeTarget run before : BeforeAndAfter
> Target : BeforeAndAfter
> AfterTarget run after : BeforeAndAfter
<Target Name="BeforeAndAfter">
<Message Text="Target : BeforeAndAfter"/>
</Target>
<!--
BOTH BeforeTarget1 and BeforeTarget2 should run before target "BeforeAndAfter"
-->
<Target Name="BeforeTarget1" BeforeTargets="BeforeAndAfter">
<Message Text="BeforeTarget1 run before : BeforeAndAfter"/>
</Target>
<Target Name="BeforeTarget2" BeforeTargets="BeforeAndAfter">
<Message Text="BeforeTarget2 run before : BeforeAndAfter"/>
</Target>
BeforeTargets
和 AfterTargets
可用于 扩展现有的构建过程 。例如,使用此属性,您可以轻松地在 CoreCompile (在 Microsoft.CSharp.targets 中定义)之前执行目标。否则,您将不得不覆盖属性
CoreCompileDependsOn
。如果没有
AfterTargets
,如果没有定义扩展点,您将无法轻松地执行一个又一个目标(目标末尾的 CallTarget
具有您可以覆盖的属性)DependsOnTargets、BeforeTargets 和 AfterTargets 执行顺序?
当
DependsOnTargets
、 BeforeTargets
和 AfterTargets
用于同一目标时,执行顺序为:DependsOnTargets
BeforeTargets
AfterTargets
<Target Name="MainTarget" DependsOnTargets="DefaultDependsOn">
<Message Text="Target : MainTarget"/>
</Target>
<Target Name="DefaultDependsOn">
<Message Text="Target : DefaultDependsOn"/>
</Target>
<Target Name="DefaultBeforeTarget" BeforeTargets="MainTarget">
<Message Text="Target : DefaultBeforeTarget"/>
</Target>
<Target Name="DefaultAfterTarget" AfterTargets="MainTarget">
<Message Text="Target : DefaultAfterTarget"/>
</Target>
Output
> Target : DefaultDependsOn
> Target : DefaultBeforeTarget
> Target : MainTarget
> Target : DefaultAfterTarget
关于msbuild - 'DependsOnTargets' 和 'AfterTargets' 有什么区别?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/2855713/
