compilation with `-lib somelib` uses hxml build file from that lib's folder

[T1mL3arn]

How to reproduce

• install git library haxelib git dragonbones https://github.com/openfl/dragonbones.git (tested for dragonbones, but any other should work, may be non-git libs work too)
• go to library git folder, e.g. dragonbones/git
• create Main.hx and build-test.hxml files there

  
  // Main.hx

class Main { static function main(){
trace('git library');
} }

```hx
# build-test.hxml

-main Main
--interp

• now create a folder for new project in some other place
• create Main.hx and build.hxml in that folder

  
  // Main.hx

class Main { static function main() { trace("actual project"); } }

```hx
# build.hxml

-lib dragonbones
-main Main
--interp

• run build.hxml

Expected result

actual project

Actual result

git library

If -lib dragonbones is commented in build.hxml then actual result is equal to expected.

Actually build-test.hxml is not executed. What happens is dragonbones/git/Main.hx shadows Main.hx of your project. I suspect if you move -main Main above -lib dragonbones you will get the expected result.

Didn't work.

[RealyUniqueName]

Oh. Perhaps it's because of the compiler "plugs in" current directory before the directory of a library. Try moving Main.hx to a directory and add that dir via -cp compiler flag before/after -lib dragonbones

[T1mL3arn]

This helped

# build.hxml

-lib dragonbones
-cp src
-main Main
--interp

So, this is not a bug and I should close the issue? In that case would be nice to have some info like "always include your project's source and main directive right after library directives to avoid the problem when library's directory's hxml files affect current project compilation" on this manual page.

This is working as intended with the latest argument taking priority. Should be mentioned on https://haxe.org/manual/compiler-usage.html.
