ispac not created when SSIS Project built
<p>With a 2012 SSDT database project and a Integration Services project within it using project deployment model, after a build, a <code>.ispac</code> file is not created for me.  Is there a setting or option that is necessary to allow this to be created?</p>

<p>The project builds successfully, and successfully creates the <code>.dacpac</code> file too.  Building from the solution or individual project, the <code>.dacpac</code> file is created, and I see both projects are built successfully when built from the solution.  I can also successfully create a <code>.SSISDeploymentManifest</code> file too.  Of course, the run the all the packages without error as well.   </p>

<p>Also, the Non-Default Properties Report shows only MaxConcurrentExecutables and EnableConfigurations for project level properties have non default values.</p>

<p>I feel like there is something small I'm missing.  Any help is appreciated.</p>
