jenv-gradle-low-ram

name	jenv-gradle-low-ram
description	Align jenv with .java-version and run Gradle reliably on low-RAM machines. Use for Java mismatch errors, Gradle OOMs, daemon memory pressure, and selecting safe build flags.
argument-hint	Describe your target task and available RAM, for example: assembleDebug on 8GB RAM

Jenv + Gradle Low-RAM Workflow

What This Skill Produces

• A shell where java and Gradle use the Java version pinned by .java-version.
• A repeatable Gradle command profile tuned for constrained memory.
• Verification checks to confirm version alignment and build stability.

When To Use

• Any time when ./gradlew is about to be invoked in this repository.
• Especially important for low-RAM machines where daemon/worker pressure can destabilize builds.
• Required when verifying that Java from .java-version is the active runtime for Gradle.

Procedure

1. Detect the required Java version.

cat .java-version

The expected output is 21.0.8. Systems in this project are expected to have jenv installed; the .java-version file is read by jenv local to pin the active JDK for the working directory.

2. Verify jenv is installed and initialized.

command -v jenv
jenv versions
jenv version
