Oracle JDK License Gate

Finds the Java lines in your build that Oracle now bills for, and the free line that replaces each one

Install

npx @readystack/oracle-jdk-license-gate file

Node 18+. The same 9 rules as the VS Code extension, from a terminal or CI.

Free

• 6 Oracle-licensed Java pulls in the bundled sample workflow _fixtures/dirty.yml: a setup-java oracle distribution, a setup-java graalvm distribution, a download.oracle.com tarball, an oraclelicense accept header, an Oracle registry image and an SDKMAN -oracle vendor suffix. Each is named with its line, its license basis, its free-window status on today's date and the free OpenJDK line that replaces it. The OpenJDK version of the same workflow reports 0. 9 rules in all, over the file you have open, with no network call.
• --rules lists every rule

With a licence ($29 once)

• $29 once. The same 9 rules swept over every file in the workspace instead of the one you have open, plus a dated evidence pack - file, line, distribution, license basis, free-window date and swap - to hand to procurement or to an Oracle audit. Team and commercial use included.

Oracle Java SE Universal Subscription is list-priced at $15 per employee per month, counting every employee in the company, not every Java install. 250 employees x $15 per employee per month x 12 months = $45,000 a year.
