Exclude Directories from the builder [message #824160]

Hi,

I have a custom DSL (.fxgraph) which gets translated by the configured
IGenerator into FXML-Files.

A project layout looks like this:

MyProject
+ src
+ my.package.bla
+ My.fxgraph
+ My.fxml (generated file)

Now the problem is that when people e.g. package things up using ant
(and some of them use the project location itself) so and so get another
new structure in it.

MyProject
+ src
+ my.package.bla
+ My.fxgraph
+ My.fxml (generated file)
+ build
+ build
+ build
+ classes.bla
+ My.fxgraph
+ My.fxml

and now the builder kicks in and generates FXML-Files once more in the
src-Folder

MyProject
+ src
+ my.package.bla
+ My.fxgraph
+ My.fxml (generated file)
+ MyProject.build
+ build
+ classes.bla
+ Test.fxml
+ build
+ build
+ build
+ classes.bla
+ My.fxgraph
+ My.fxml

I hope you get the problem with this description.

So my question from the title is it somehow possible to restrict the
builder to only look at src-directories, or do have to check this
manually in the IGenerator#doGenerate() which would have the draw back
that I create a dependency on JDT there because need to check if the
given Resource is found inside the source-container.

Another possibility would be to exclude the .fxgraph files from being copied to the build target (as is quite common with non-generated/-compiled artifacts).

If that's language specific, the easiest way is to provide your own
IResourceDescription.Manager that returns an empty IResourceDescription
on getResourceDescription(Resource) for build dir files and returns
false on isAffected, if the candidate is in your build directory.

If it should be for all languages, you could hook in earlier in the
XtextBuilder or ToBeBuildComputer. In this case, you have to modify the
SharedStateModule.

Hi Tom,

you may want to override
org.eclipse.xtext.ui.resource.DefaultResourceUIServiceProvider.canHandle(URI)
and return false if the uri does not point to a source folder.

Regards,
Sebastian
