Linux Packages of Eclipse Adoptium

We package for Debian, Red Hat, SUSE (e.g. DEB and RPM based) Linux distributions.

The current implementation to build the packages involves using Gradle to call a small Java program. That Java program spins up a Docker container, installing the base O/S and its packaging tools, and then looping over configuration to create the various packages and signing them as appropriate with the (Eclipse Foundation as a default) signing service.

TODO You can then optionally upload those packages to a package repository of your choice. The default Adoptium package repository is https://packages.adoptium.net/ui/packages. The packages are built and uploaded by Jenkins pipeline job defined by Jenkinsfile

Prerequisites

To run this locally

  • You will need to have Docker 20.10+ installed and running.
  • You will need to have Java 8+ installed.
  • You will need to have a minimum of 8GB of RAM on your system (the build required 4GB).

Building the Packages

Builds take at least ~5-15 minutes to complete on a modern machine. Please ensure that you have Docker installed and running.

You'll want to make sure you've set the exact versions of the binaries you want package in the:

  • Alpine Based - {jdk,jre}/alpine/src/main/packaging/<vendor>/<version>/AKKBUILD files.
  • Debian Based - {jdk,jre,ca-certificates}/debian/src/main/packaging/<vendor>/<version>/debian/rules files.
  • Red Hat Based - {jdk,jre}/redhat/src/main/packaging/<vendor>/<version>/<vendor>/<vendor>-<version>-jdk.spec files.
  • SUSE Based - {jdk,jre}/suse/src/main/packaging/<vendor>/<version>/<vendor>/<vendor>-<version>-jdk.spec files.

In all the examples below you'll need to replace the following variables:

  • Replace <version> with 8|11|17|19
  • Replace <vendor> with temurin|dragonwell
  • Replace <platform> with Alpine|Debian|RedHat|Suse
  • Replace <type> with Jdk|Jre (or CaCertificates for the Debian platform)

Notes:

  • Not all combinations are possible, i.e., for some vendors we might only provide certain versions, or types.
  • For Debian we provide a separate package with Certification Authority certificates.

Build all packages for a version

export DOCKER_BUILDKIT=1
export _JAVA_OPTIONS="-Xmx4g"
./gradlew clean package checkPackage -PPRODUCT=<vendor> -PPRODUCT_VERSION=<version>

The scripts roughly work as follows:

  • Gradle Kickoff - The various package<type><platform> tasks in subdirectories under the jdk (or jre) directory all have a dependency on the packageJDK (packageJRE) task, which in turn has a dependency on the package task (this is how Gradle knows to trigger each of those in turn).
  • package<platform> Tasks - These tasks are responsible for building the various packages for the given platform. They fire up the Docker container (A Dockerfile is included in each subdirectory), mount some file locations (so you can get to the output) and then run packaging commands in that container.
  • check<platform> Tasks - Test containers are used to install the package and run the tests in src/packageTest/java/packaging on them.
  • task package --> [task package<type>](/build.gradle) --> [task package<type><DISTRO>](/<vendor>/build.gradle )
  • task checkPackage --> [task check<type>Package](/build.gradle) --> [task check<type><DISTRO>](/<vendor>/build.gradle )

Build a Debian specific package for a version

  • replace <version> with 8|11|17|19
  • replace <vendor> with temurin|dragonwell
  • Replace <type> with Jdk|Jre
export DOCKER_BUILDKIT=1
export _JAVA_OPTIONS="-Xmx4g"
./gradlew clean package<type>Debian check<type>Debian --parallel -PPRODUCT=<vendor> -PPRODUCT_VERSION=<version>

Build a Red Hat specific package for a version

  • replace <version> with 8|11|17|19
  • replace <vendor> with temurin|dragonwell
export DOCKER_BUILDKIT=1
export _JAVA_OPTIONS="-Xmx4g"
./gradlew clean packageJdkRedHat checkJdkRedHat --parallel -PPRODUCT=<vendor> -PPRODUCT_VERSION=<version>

Build a SUSE specific package for a version

  • replace <version> with 8|11|17|19
  • replace <vendor> with temurin|dragonwell
export DOCKER_BUILDKIT=1
export _JAVA_OPTIONS="-Xmx4g"
./gradlew clean packageJdkSuse checkJdkSuse --parallel -PPRODUCT=<vendor> -PPRODUCT_VERSION=<version>

GPG Signing RPMs/APKs

In order to GPG sign the generated RPMs/APKs you must add the following argument to the gradlew command:

  • replace <DISTRO> with Alpine|RedHat|Suse
  • replace <version> with 8|11|17|19
  • replace <vendor> with temurin|dragonwell
./gradlew packageJdk<DISTRO> --parallel -PPRODUCT=<vendor> -PPRODUCT_VERSION=<version> -PGPG_KEY=</path/to/private/gpg/key>

Building from local files

In order to build a jdk/jre package for RPM or DEB from local tar.gz file(s), put both the tar.gz and the sha256.txt files in an empty input directory. If the vendor supports building locally, then one can specify this directory when running ./gradlew clean using the -PINPUT_DIR flag

Example:

./gradlew clean packageJdkRedHat checkJdkRedHat --parallel -PPRODUCT=<vendor> -PPRODUCT_VERSION=<version> -PARCH=<architecture> -PINPUT_DIR=<path/to/input/directory>

NOTE if building an RPM: Make sure to update global variables upstream_version and spec_version in the corresponding spec-file to match the version number of the jdk/jre RPM that you are building. (This is how RPM determines the version number of the resulting package)

Note if building an DEB: Make sure to update the changelog file in the corresponding vendor's debian folder so the most recent entry is about the version number of the jdk/jre DEB that you are building. (This is how DEB determines the version number of the resulting package)

Building SRPMs and RPMs Directly

If you do not require testing or advanced build support, it is perfectly fine to eschew the Gradle-based build and to directly build SRPMs and RPMs using the spec files in the repository.

In this example, we are using the existing spec files for the Temurin 11 JDK to create an SRPM and then rebuild that SRPM into a binary RPM. It supports building it for the current target architecture or for a different one than the host system by specifying vers_arch.

Prerequisites: rpm-build and rpmdevtools packages are installed. For example:

$ rpm -q rpmdevtools rpm-build
rpmdevtools-9.3-3.fc33.noarch
rpm-build-4.16.1.3-1.fc33.x86_64

Produce a Source/Binary RPM for x86_64

Consider this RPM build where x86_64 is the build hosts' architecture. Download the release blobs and associated sources. Suppose build rpm for jdk11 for target architecture x86_64

cd linux/jdk/redhat/src/main/packaging/temurin/11
mkdir temurin_x86_64
pushd temurin_x86_64
spec=$(pwd)/temurin-11-jdk.spec
spectool --gf ${spec}
sha256sum -c *.sha256.txt

Create a SRPM:

rpmbuild --define "_sourcedir $(pwd)" --define "_specdir $(pwd)" \
         --define "_builddir $(pwd)" --define "_srcrpmdir $(pwd)" \
         --define "_rpmdir $(pwd)" --nodeps -bs ${spec}

Build the binary from the SRPM:

rpmbuild --define "_sourcedir $(pwd)" --define "_specdir $(pwd)" \
         --define "_builddir $(pwd)" --define "_srcrpmdir $(pwd)" \
         --define "_rpmdir $(pwd)" --rebuild *.src.rpm

Building for a different architecture

In order to produce RPMs on an x86_64 build host for the s390x target architecture, use the --target switch to rpm-build to build for a different architecture. Suppose the host architecture is x86_64 and we want to build for target architecture s390x:

rpmbuild --define "_sourcedir $(pwd)" --define "_specdir $(pwd)" \
         --define "_builddir $(pwd)" --define "_srcrpmdir $(pwd)" \
         --define "_rpmdir $(pwd)" --target s390x --rebuild *.src.rpm
