# 🔍 Description
I found the [previous change](https://github.com/apache/kyuubi/pull/6606) breaks compatibility in some shell interpreters, for example `[ ! -f "$MVN_BIN" ]`, `[ $MVN_DETECTED_VERSION != $MVN_VERSION ]` are not supported in ubuntu dash, which fails the CI https://github.com/apache/kyuubi/actions/runs/10347069575/job/28636666290
