Dependency pinning and checksum verification

Dependency pinning

Gradle lock file's is used to pin the version number of all dependencies. In this way, when there are versions with wildcards (e.g. 1.3+) gradle is forced to use the specific version listed on the lock file at the time of generation. The lock file doesn't check the checksum of dependency, cause gradle has a different mechanism to achieve this. To enable dependency pinning verification this line need to be added to build.gradle file:

dependencyLocking {
    lockMode = LockMode.STRICT
    lockAllConfigurations()
}

Dependency checksum verification

You can generate a file under the project's gradle folder called verification-metadata.xml. This file contains the dependency hashes and optionally also the pgp signatures (if enabled). When gradle runs a build or downloads dependencies it automatically checks if this file is present and returns error if a dependency is not present in the verification-metadata.xml file or if its signature or checksum has changed.

How to generate both?

To generate dependency pinning or the checksum file, gradle provides two flag to use when running a task. --write-locks to generate lock file and --write-verification-metadata to generate checksum file. With -DskipTests you can skip test without getting coverage errors. The following commands generates both during build task:

gradle --write-locks --write-verification-metadata sha256 -DskipTests quarkusBuild --no-build-cache --refresh-dependencies gradle --write-locks --write-verification-metadata sha256 -DskipTests quarkusDev --no-build-cache --refresh-dependencies

NOTE: Sometimes the local gradle cache can inhibit exploration of some dependencies so it is good to perform file generation without using cache with --no-build-cache --refresh-dependencies

How to add new dependency?

Add the new dependency/plugin or something else to gradle file and then re-run the command listed above.

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./gradlew quarkusDev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

gradle --write-locks --write-verification-metadata sha256 build --no-build-cache --refresh-dependencies refers to https://docs.gradle.org/current/userguide/dependency_verification.html#sub:enabling-verification and https://docs.gradle.org/8.5/userguide/dependency_locking.html

Packaging and running the application

The application can be packaged using:

./gradlew build

It produces the quarkus-run.jar file in the build/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the build/quarkus-app/lib/ directory.

The application is now runnable using java -jar build/quarkus-app/quarkus-run.jar.

If you want to build an über-jar, execute the following command:

./gradlew build -Dquarkus.package.type=uber-jar

The application, packaged as an über-jar, is now runnable using java -jar build/*-runner.jar.

Creating a native executable

You can create a native executable using:

./gradlew build -Dquarkus.package.type=native

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

./gradlew build -Dquarkus.package.type=native -Dquarkus.native.container-build=true

You can then execute your native executable with: ./build/terminal-registry-1.0.0-SNAPSHOT-runner
