Examples with GroovyJarFile org.gradle.api.internal.plugins.GroovyJarFile used on opensource projects

Example 1 with GroovyJarFile

use of org.gradle.api.internal.plugins.GroovyJarFile in project gradle by gradle.

the class GroovyRuntime method inferGroovyClasspath.

/**
     * Searches the specified class path for Groovy Jars ({@code groovy(-indy)}, {@code groovy-all(-indy)}) and returns a corresponding class path for executing Groovy tools such as the Groovy
     * compiler and Groovydoc tool. The tool versions will match those of the Groovy Jars found. If no Groovy Jars are found on the specified class path, a class path with the contents of the {@code
     * groovy} configuration will be returned.
     *
     * <p>The returned class path may be empty, or may fail to resolve when asked for its contents.
     *
     * @param classpath a class path containing Groovy Jars
     * @return a corresponding class path for executing Groovy tools such as the Groovy compiler and Groovydoc tool
