Read attributes of MSBuild custom tasks via events in the Logger
- by gt
I am trying to write a MSBuild logger module which logs information when receiving TaskStarted events about the Task and its parameters.
The build is run with the command:
MSBuild.exe /logger:MyLogger.dll build.xml
Within the build.xml is a sequence of tasks, most of which have been custom written to compile a (C++ or C#) solution, and are accessed with the following custom Task:
<DoCompile Desc="Building MyProject 1" Param1="$(Param1Value)" />
<DoCompile Desc="Building MyProject 2" Param1="$(Param1Value)" /> <!-- etc -->
The custom build task DoCompile is defined as:
public class DoCompile : Microsoft.Build.Utilities.Task
{
[Required]
public string Description { set { _description = value; } }
// ... more code here ...
}
Whilst the build is running, as each task starts, the logger module receives IEventSource.TaskStarted events, subscribed to as follows:
public class MyLogger : Microsoft.Build.Utilities.Logger
{
public override void Initialize(Microsoft.Build.Framework.IEventSource eventSource)
{
eventSource.TaskStarted += taskStarted;
}
private void taskStarted(object sender, Microsoft.Build.Framework.TaskStartedEventArgs e)
{
// write e.TaskName, attributes and e.Timestamp to log file
}
}
The problem I have is that in the taskStarted() method above, I want to be able to access the attributes of the task for which the event was fired.
I only have access to the logger code and cannot change either the build.xml or the custom build tasks.
Can anyone suggest a way I can do this?
