Error condition (target)

Hello,
I have a question regarding the Error Condition. In case I have a target and this target depends on some other 2 targets how can I insure that the condition will be verified before the other tartgets will run?

(For example :

<Target Name="Publish" DependsOnTargets="Compile">
<Error Condition="'$(Revision)' == ''" Text="Revision environment variable must be specified in order to build target: Publish"></Error>

</Target>

How can I insure that Error Condition will run before running the Compile target?

Thanks!

You could add another DependsOnTarget that does the check. e.g.

<Project ToolsVersion="3.5" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<Target Name="Publish" DependsOnTargets="CheckState;Compile"/>

<Target Name="CheckState">
<Error Condition="'$(Revision)' == ''" Text="Revision environment variable must be specified in order to build target: Publish"></Error>
</Target>

<Target Name="Compile"/>
</Project>

Hi,
As Mike stated you should create another target, CheckState, which will execute the Error task. I would also suggest placing the CheckState target on the DependsOnTargets list for the Publish and Compile target. That target should be on the DependsOnTargets list for all targets which must assert that condition.
