+ %% Regression test for https://github.com/rebar/rebar/issues/249
+ %%
+ %% Root cause: We didn't have per-project .rebar/erlcinfo but just one in
+ %% <base_dir>/.rebar/erlcinfo.
+ %%
+ %% Solution: Ensure every project has its own .rebar/erlcinfo
+ %%
+ %% For the bug to happen, the following conditions must be met:
+ %%
+ %% 1. <base_dir>/rebar.config has erl_first_files
+ %% 2. one of the 'first' files depends on another file (in this
+ %% case via -include_lib())
+ %% 3. a sub project's rebar.config, if any, has no erl_first_files entry
+ %%
+ %% Now because erl_first_files is retrieved via rebar_config:get_list/3,
+ %% base_dir/rebar.config's erl_first_files is inherited, and because we had
+ %% a shared <base_dir>/.rebar/erlcinfo instead of one per project, the
+ %% cached entry was reused. Next, while compiling the sub project
+ %% rebar_erlc_compiler:needs_compile/3 gets a last modification time of
+ %% zero for the 'first' file which does not exist inside the sub project.
+ %% This, and the fact that it has at least one dependency, makes
+ %% needs_compile/3 return 'true'. The root cause is that we didn't have per
+ %% project .rebar/erlcinfo. For <base_dir>/.rebar/erlcinfo to be populated,
+ %% base_dir has to be compiled at least once. Therefore, after the first
+ %% compile any compile processing the sub project will fail because
+ %% needs_compile/3 will always return true for the non-existent 'first'
+ %% file.
