GradleRIO: OpenCV Native libraries could not be loaded

I am using 2017.2.3. I have redeployed and reimaged.

OpenCV Native Libraries could not be loaded.
Please try redeploying, or reimage your roboRIO and try again.

Edit: I just realized the error after “Robot program starting” is mine, I’m referring to the one above it.

Using an older version of the plugin and OpenCV until this issue is fixed: https://github.com/Open-RIO/GradleRIO/issues/39 — committed to Team1091/FRC-2017-Steamworks-Gradle by stewsters 7 years ago

I’m going to bump real quick for when I take a look at this issue in the newer releases.

It may be possible to make 3.1.0 and 3.2.0 both work in the same plugin version, given some clever version checking. For <=3.1.0, the artifact is opencv-jni-VERS-linux-arm, while from 3.2.0 onwards it is opencv-jni-VERS-linuxathena
