Babel Maven Plugin

Plugin lets you to execute Babel transcription for given JavaScript files. It requires no npm or node.js, it is plain Java project which works perfectly combined with WebJars.

Maven coords

<dependency>
  <groupId>com.jarslab.maven</groupId>
  <artifactId>babel-maven-plugin</artifactId>
  <version>1.2</version>
</dependency>

Settings, ie buttons and knobs

• verbose - no surprises, the execution becomes a bit more talkative (default: false),
• parallel - if true will run files transpilation in parallel (on ForkJoin pool) (default: true),
• encoding - will apply chosen encoding during files operations (read/write) (default: Charset.defaultCharset()),
• babelSrc - readable path to standalone(!) Babel sources. It can be provided from WebJars dependency, minified or development version,
• sourceDir - base path for JavaScript files you are going to translate,
• targetDir - result path, note that all sub-directories from sourceDir will be preserved,
• jsFiles - list of JavaScript files (static) from sourceDir to translate,
• jsIncludes - list of JavaScript files (with simple masks */?),
• jsExcludes - list of exceptions for jsIncludes,
• prefix - optional prefix applied for every translated file,
• presets - presets for Babel execution (default: es2015),
