Scaling Java Compilation: From javac to Large Projects

Compiling a single Java file with a basic command is straightforward, but managing compilation for projects with tens of thousands of files requires a deeper understanding of compiler mechanics. When scale increases, standard build approaches can slow down your development loop or fail entirely. This course guides you through the core mechanics of Java compilation, helping you transition from basic command-line execution to optimizing large-scale build pipelines. What you'll learn: - Understand the core mechanics of javac and alternative compilers like the Eclipse Compiler for Java. - Manage large-scale compilation by structuring source files and utilizing compiler argument files. - Optimize build performance through incremental compilation and compilation avoidance techniques. - Configure annotation processors and analyze their impact on compilation speed. - Leverage modern Java module systems to enforce clean boundaries and improve build efficiency. - Troubleshoot complex compiler errors, memory limits, and classpath conflicts. You will start with fundamental compiler concepts and command-line execution before exploring performance tuning, dependency management, and modern build optimization strategies. This course is designed for Java developers who want to master the build process, with no prior compiler design experience required. Start reading to master the mechanics of Java compilation at scale.
