Example 6 with JavacFileManager

use of org.eclipse.ceylon.langtools.tools.javac.file.JavacFileManager in project ceylon by eclipse.

the class LanguageCompiler method getSrcDir.

// FIXME: this function is terrible, possibly refactor it with getPackage?
private File getSrcDir(File sourceFile) throws IOException {
    Iterable<? extends File> prefixes = ((JavacFileManager) fileManager).getLocation(StandardLocation.SOURCE_PATH);
    File srcDirFile = FileUtil.selectPath(prefixes, sourceFile.getPath());
    if (srcDirFile != null) {
        return srcDirFile;
    } else {
        // This error should have been caught by the tool chain
        throw new RuntimeException(sourceFile.getPath() + " is not in the current source path");
    }
}

Example 7 with JavacFileManager

use of org.eclipse.ceylon.langtools.tools.javac.file.JavacFileManager in project ceylon by eclipse.

the class LanguageCompiler method addModuleDescriptors.

// This is a bit of a hack, but if we got passed a list of resources
// without any accompaning source files we'll not be able to determine
// the module to which the resource files belong. So to try to fix that
// we see if a module file exists in the source folders and add it to
// the list of source files
private List<JavaFileObject> addModuleDescriptors(List<JavaFileObject> sourceFiles, List<JavaFileObject> resourceFiles) {
    List<JavaFileObject> result = sourceFiles;
    JavacFileManager dfm = (JavacFileManager) fileManager;
    for (JavaFileObject fo : resourceFiles) {
        String resName = JarUtils.toPlatformIndependentPath(dfm.getLocation(CeylonLocation.RESOURCE_PATH), fo.getName());
        JavaFileObject moduleFile = findModuleDescriptorForFile(new File(resName));
        if (moduleFile != null && !result.contains(moduleFile)) {
            result = result.append(moduleFile);
        }
    }
    return result;
}

Example 8 with JavacFileManager

Example 9 with JavacFileManager

use of org.eclipse.ceylon.langtools.tools.javac.file.JavacFileManager in project ceylon by eclipse.

the class LanguageCompiler method isResource.

private boolean isResource(JavaFileObject fo) {
    // make sure we get a proper normalized abslute path
    String fileName = FileUtil.absoluteFile(new File(fo.toUri().getPath())).getPath();
    // now see if it's in any of the resource paths
