Examples with AbstractFile scala.reflect.io.AbstractFile used on opensource projects

Example 1 with AbstractFile

use of scala.reflect.io.AbstractFile in project zeppelin by apache.

the class SparkDependencyResolver method updateCompilerClassPath.

private void updateCompilerClassPath(URL[] urls) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException {
    JavaPlatform platform = (JavaPlatform) global.platform();
    MergedClassPath<AbstractFile> newClassPath = mergeUrlsIntoClassPath(platform, urls);
    Method[] methods = platform.getClass().getMethods();
    for (Method m : methods) {
        if (m.getName().endsWith("currentClassPath_$eq")) {
            m.invoke(platform, new Some(newClassPath));
            break;
        }
    }
    // NOTE: Must use reflection until this is exposed/fixed upstream in Scala
    List<String> classPaths = new LinkedList<>();
    for (URL url : urls) {
        classPaths.add(url.getPath());
    }
    // Reload all jars specified into our compiler
    global.invalidateClassPathEntries(scala.collection.JavaConversions.asScalaBuffer(classPaths).toList());
}

Example 2 with AbstractFile

use of scala.reflect.io.AbstractFile in project zeppelin by apache.

the class SparkDependencyResolver method mergeUrlsIntoClassPath.

private MergedClassPath<AbstractFile> mergeUrlsIntoClassPath(JavaPlatform platform, URL[] urls) {
    IndexedSeq<ClassPath<AbstractFile>> entries = ((MergedClassPath<AbstractFile>) platform.classPath()).entries();
    List<ClassPath<AbstractFile>> cp = new LinkedList<>();
    for (int i = 0; i < entries.size(); i++) {
        cp.add(entries.apply(i));
    }
    for (URL url : urls) {
        AbstractFile file;
        if ("file".equals(url.getProtocol())) {
            File f = new File(url.getPath());
            if (f.isDirectory()) {
                file = AbstractFile.getDirectory(scala.reflect.io.File.jfile2path(f));
            } else {
                file = AbstractFile.getFile(scala.reflect.io.File.jfile2path(f));
            }
        } else {
            file = AbstractFile.getURL(url);
        }
        ClassPath<AbstractFile> newcp = platform.classPath().context().newClassPath(file);
        // distinct
        if (cp.contains(newcp) == false) {
            cp.add(newcp);
        }
    }
    return new MergedClassPath(scala.collection.JavaConversions.asScalaBuffer(cp).toIndexedSeq(), platform.classPath().context());
