Building Projects
You must validate and compile an Application Platform project before you can publish it. During the build phase, Application Platform compiles the project source code and produces additional files, for example metadata files. However, Application Platform does not perform any additional bundle-related activities when building a project.
You can build your project either with one of the standard project builders in Designer, or with one of the custom project builders for Application Platform projects. However, Application Platform projects are build with all of the project builders that are automatically configured when you apply the Application Platform Core project facet.
