don't lose erl_opts when compiling for tests

Error dep parsing

generalize some temporary directory handling and add it to `rebar_file_utils`

swap `file:list_dir` for `file:list_dir_all` due to nonexistence of latter prior to r16x

do provider returns the error of the first provider to fail and stops

no skip warning for seen dep that has locked version

(in `rebar_file_utils`)

change more instances of mistyped `erl_first_modules` to `erl_first_files`

`erl_first_files`

fixes #99

don't mark dep as seen before calling handle_dep

replace single profile atom in providers with list of profiles

when compiling `common_test` or `eunit` use the same tmp dir

from run to run

change `rebar_app_into` to `rebar_app_info` in typespecs

test providers

`common_test` and `eunit` providers

option handling

in presence of keys defined multiple times

do not include dir . in relx lib paths it will break lib discovery

Update README.md

compiles common test files in a temporary dir (or a user specified
dir) and runs tests without leaving artifacts in the source tree

precompile tests using `rebar.config` and disable autocompile so
project specific options are used

fixes #62

compiles apps and eunit test files in a temporary dir (or a user
specified dir) and runs tests without leaving artifacts in the
source tree

automatically defines the 'TEST' macro if not already defined and
adds `test` to `src_dirs` to allow for eunit test files outside `src`

overrides working except for transitive dep inheritance with lock file

point compiler to the right config value for which files need to be compiled first

compiled first

Adding tests for checkouts being found & compiled
