jar-pack

Is a small Maven project which packs given binary (e.g, JRE) into a JAR with a POM. Result can be added to a private Maven repository and referenced by your builds. This can be handy for those who check in the JRE into the source control system, and looking for the ways to reduce its size.

Creating a JAR

1. Copy your JRE to /data directory. Note that it has a /bin sub directory with java or java.exe and /lib with rt.jar in it.
2. Edit <artifactId> and <version> values in pom.xml file as appropriate. Make note of the comments as to the format.
3. Run mvn clean package.
4. Your jar and pom files would be in the /target directory.
5. Upload (deploy) your jar and pom to your company's private Maven repository.

Using the JAR as a Java library

In rear situations you would need to access JRE binary from within a Java application as a resource. Resulting JAR offers the following interface for your convenience:

    ServiceLoader.load(PackedJre.class).forEach(jre ->
    {
        System.out.println("JRE found: "+ jre.getVendor() +" - "+ jre.getPlatform() +" - "+ jre.getVersion() +" - "+ jre.getPath());
    });

or try this to get individual file entries along with MD5s:

    PackedJres.getAll().forEach(jre ->
    {
        jre.getEntries().forEach(file -> {
            System.out.println(file.getName() +", MD5:"+ file.getMD5());
        });
    });

The JRE

Consider getting you JRE from https://bintray.com/jetbrains/intellij-jdk
