How to suppress all warnings using MSBuild

In Jenkins

• Happened upon this Googling "how to suppress MSBuild warnings in Jenkins"
• So much noise like the following in our console output, couldn't find the meat

  Missing XML comment for publicly visible type or member
  

• Inherited Jenkins on a Windows server

---

1. Manage Jenkins > Global Tool Configuration > MSBuild
2. Add /clp:ErrorsOnly to the Default parameters

The best way is to fix the issues that are causing the warnings.

If you must ignore the warnings (e.g. you have inherited a project with so many that you can't see the wood for the trees), you could try changing the WarningLevel property, http://msdn.microsoft.com/en-us/library/13b90fz7.aspx

If you would like to suppress MSB3270 only then you can set in project file just

<PropertyGroup>
  <ResolveAssemblyWarnOrErrorOnTargetArchitectureMismatch>
    None
  </ResolveAssemblyWarnOrErrorOnTargetArchitectureMismatch>
</PropertyGroup>

msbuild /clp:ErrorsOnly
