jdkget
JdkGet is a Java utility that allows you to download Linux/OSX/Windows JDKs from Oracle, and extract them in arbitrary directories in a fully automated way.
To install a JDK you can use something like the following:
JdkReleases rels = JdkReleases.get();
ITransport transport = createTransportFactory().createTransport();
JdkRelease rel = rels.select("8u201");
JCE jce = rels.getJCE(rel.getVersion());
JdkGetter getter = new JdkGetter(transport, StdOutput.INSTANCE);
File outputDir = ...;
getter.getJdk(rel, jce, Arch.autodetect(), outputDir);
You can find a list of available JDKs here.

Building
To build JDKGet use the Maven Wrapper script provided with the project:
./mvnw clean install
Integration testing
Testing downloads of all versions can be performed using it profile and providing your OTN credentials:
mvn clean verify -Pit -Dio.takari.jdkget.username=<otnUsername> -Dio.takari.jdkget.password=<otnPassword>
The result will produce a shaded JAR in the target/ directory which can we executed using java -jar jdkget-${version}.jar
*nix and Solaris
Downloads and extracts a .tar.gz, simple and easy
OSX
This will retrieve the Java equivalent of a turducken: the GZipped CPIO files of the JDK, wrapped in an XAR file, inside an HFS disk image. Can't we just use TarGz files? No, no, that would be too easy.
Windows
Similar to OSX, but with tools.zip (with some jars pack200'd) in CAB in EXE in EXE.
