JavaBuild

This is just an experiment i'm making to scratch an itch, feel free to chime in with ideas but don't expect too much from it for now

What if Java had something similar to the Swift Package Manager, a straightforward extensible Java build tool with a configuration written completely in Java?

Usage

JavaBuild is a build tool (ANT,Maven,Gradle,...) that uses configuration files written in pure Java. Every project has a Build.java file that contains all the configuration to compile the module (the basic unit that JavaBuild manages, in other words a project with some sources).

Init a project (it creates the standard Maven src directory and a simple Build.java):

./javabuild --init

Compile the content of a project (you'll find the result .class files in target/):

./javabuild --compile

Build a jar (you'll find the resulting jar in target/):

./javabuild --jar

Clean the project removing all artifacts built by JavaBuild:

./javabuild --clean

TODO

• It should be able to build itself
• In dire need of a refactoring
• Add unit/integration tests
• Add support for test (specific command)
• Actually reading and compiling Build.java
• Build a simple javabuild-ready Hello World
• Build a project with multiple interdependent java files, solving the dependency graph, incremental build
• Support external local dependencies (i.e jar in a folder)
• Support external dependencies via maven central or the similar gradle thing
• Support external javabuild-ready dependencies from github, get them, build them, use them
• Allow to include other file types in the resulting jar
• Configurable output: jar,fatjar,war,whatever
