Log is noisy in CI

Question Description

Running turtle in CI like this

- turtle build:android
    --config app.json
    --release-channel $CHANNEL
    --keystore-path ./expo-project.jks
    --keystore-alias $EXPO_ANDROID_KEYSTORE_ALIAS
    --type app-bundle
    -o $ARTIFACT_PATH

produces noisy logs like this

Sep 21 09:25:40 turtle[6204] INFO: 30715493 kotlin/text/RegexExtensionsKt.kotlin_metadata (OK - compressed) platform: "android" buildPhase: "verifying apk alignment" source: "stdout"

Example log: https://travis-ci.org/github/denniske/aoe2companion/jobs/728924795

Is there an option to switch the logging output format to single line?
