⁠openshift-gradle_wrapper

OpenShift S2I builder image for projects using the Gradle wrapper.

Assumes the build task will build and test the artifact. If there is another task to run, set the GRADLE_BUILD_TASK environment variable.

Assumes the build task produces an executable war or jar with an embedded server. The artifact is started with arguments as follows:

  java -jar \
     -Dserver.address=${HOST} -Dserver.port=${PORT} \
     -Dgrails.server.address=${HOST} -Dgrails.server.port=${PORT} \
     ${JAVA_OPTS} \
     "${ARTIFACT}" \
     host=${HOST} port=${PORT}

Using the Gradle wrapper with your project means the particular version of Gradle you want to use will be downloaded on-demand. This builder has OpenJava 1.8.0 installed on CentOS 7.

A proxy repository for artifacts can be configured by setting the GRADLE_REPO environment variable, such as:

GRADLE_REPO=http://repo:9081/content/groups/public/

The GRADLE_OPTS and/or GRADLE_BUILD_OPTS variables can be set to pass custom options to the Gradle build. Currently these do the same thing. A future release may apply GRADLE_OPTS to all Gradle invocations and GRADLE_BUILD_OPTS only to the build invocation.

This builder supports incremental builds. Everything in the Gradle user home is archived for later builds. You can get this value in your Gradle build using project.gradle.getGradleUserHomeDir(). For example:

def pathToHoldMyCachedFile = new File(project.gradle.getGradleUserHomeDir(), "myfile.txt")
pathToHoldMyCachedFile.text = "data"

⁠Image Stream

The builder can be imported into OpenShift using the file at image-streams-gradle_wrapper.json⁠

oc login # Use admin credentials
oc create -f image-streams-gradle_wrapper.json -n openshift
