OCI Java SDK Maven Native Image Executable Example

This folder contains an example of using the SDK with the Streaming service. It depends on the oci-java-sdk-streaming module as well as oci-java-sdk-common-httpclient-jersey, therefore using the OCI SDK Jersey client implementation.

The build configures the Native Maven Plugin to allow building executables with GraalVM Native Image.

Run the example

To run the example:

• Set the oci.java.sdk.version property in the pom.xml file.
• (Optionally) Install the required dependencies by running from the root directory:

  mvn install -pl bmc-streaming,bmc-common-httpclient-choices/bmc-common-httpclient-jersey -am -DskipTests
  mvn install -pl bmc-bom

• Set your compartment id and execute the example with the required arguments:

  export COMPARTMENT_OCID="..."
  mvn install exec:java -Dexec.args=$COMPARTMENT_OCID

It is possible to execute any other example from the bmc-examples module by replacing the dependencies, moving a different example java file and setting the mainClass Maven property. To use Jersey3 simply change the oci-java-sdk-common-httpclient-jersey to oci-java-sdk-common-httpclient-jersey3 dependency.

Run the example as Native Image executable

To execute the example as a GraalVM native image executable run:

• Perform the first 2 steps as above if required.
• Build the native executable:

  mvn clean package -Pnative

• Run the native executable with the required arguments:

  export COMPARTMENT_OCID="..."
  ./target/oci-java-sdk-examples $COMPARTMENT_OCID

Building with GraalVM Java8

Prior to building with Java8 GraalVM distribution, perform these steps:

• Change the native-maven-plugin.version to 0.9.25 or prior.
• Add the following build arguments in the configurtion of the native build plugin:

  <plugin>
    <groupId>org.graalvm.buildtools</groupId>
    <artifactId>native-maven-plugin</artifactId>
    ...
    <configuration>
      ...
      <buildArgs>
        <buildArg>--allow-incomplete-classpath</buildArg>
        <buildArg>--report-unsupported-elements-at-runtime</buildArg>
      </buildArgs>
    </configuration>
  </plugin>
