[INFO] [stderr] warning: output filename collision.
[INFO] [stderr] The bin target `echo-adb` in package `echo-adb v1.0.1 (/opt/rustwide/workdir)` has the same output filename as the lib target `echo_adb` in package `echo-adb v1.0.1 (/opt/rustwide/workdir)`.
[INFO] [stderr] Colliding filename is: /opt/rustwide/target/doc/echo_adb/index.html
[INFO] [stderr] The output filenames should be unique.

[INFO] [stderr] the same path; see <https://github.com/rust-lang/cargo/issues/6313>.
