ojdkbuild open-source project

ojdkbuild is an independent open-source project that produces community-driven Windows binaries of the Java Development Kit, offering a clean redistribution of the OpenJDK codebase without vendor-specific additions. Its single, self-contained package compiles the unmodified upstream sources into native MSI and ZIP formats that integrate smoothly with Windows deployment tools, making it a lightweight alternative to commercial JDK distributions. Typical use cases include powering local development environments for Spring Boot, Jakarta EE, Android Gradle or Maven builds, driving CI servers such as Jenkins or GitLab Runner, hosting servlet containers like Apache Tomcat and Jetty, and executing big-data frameworks such as Apache Spark, Elasticsearch or Kafka on Windows nodes. System administrators appreciate the silent-install MSI, while educators value the unrestricted redistribution license for classroom labs. Because the build omits proprietary plugins and telemetry, security teams can audit every artifact against published checksums and OpenJDK commit hashes. ojdkbuild supports both LTS feature releases and quarterly security updates, giving projects a predictable upgrade cadence that tracks the upstream release train. All current ojdkbuild OpenJDK builds are available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the latest upstream version and allowing users to queue multiple JDK feature releases for unattended batch installation.
