错误org.gradle.internal.exceptions.LocationAwareException：任务执行失败＆＃39;：app：compileDebugJavaWithJavac

Question

我在设计项目时遇到问题。我正在构建一个新闻应用程序，它使用Guardian网站的查询并解析JSON响应。 我使用了标签和片段。 当我试图修复initLoader时，我的app停止了以便能够编译

package com.example.android.mynewsstand;
import android.app.LoaderManager;
import android.content.Loader;
import android.os.Bundle;
import android.app.Fragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;
import java.util.ArrayList;
import java.util.List;
public class EconomyFragment extends Fragment implements LoaderManager.LoaderCallbacks<List<News>> {

    /** Adapter for the list of earthquakes */
    private NewsListsAdapter mAdapter;
    private static final String GUARDIAN_QUERY = "https://content.guardianapis.com/search?q=sports&show-elements=image&api-key=test&show-fields=thumbnail&show-tags=contributor&order-by=newest";
    public static final String LOG_TAG = SportsFragment.class.getName();

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.news_item_list, container, false);

        getActivity().getLoaderManager().initLoader(0, null, this).forceLoad();

        final ArrayList<News> news = new ArrayList<News>();


        mAdapter = new NewsListsAdapter(getActivity(), news);
        ListView listView = (ListView) rootView.findViewById(R.id.list);
        listView.setAdapter(mAdapter);
        return rootView;
       }

    @Override
    public Loader<List<News>> onCreateLoader(int i, Bundle bundle) {
        // Create a new loader for the given URL
        Log.i(LOG_TAG, "test: onCreateLoader() called...");
        return new NewsLoader(getActivity().getApplication(), GUARDIAN_QUERY);
    }
    @Override
    public void onLoadFinished(Loader<List<News>> loader, List<News> news) {
        // Clear the adapter of previous earthquake data
        Log.i(LOG_TAG, "test onLoadFinished() called...");
        mAdapter.clear();

        // Clear the adapter of previous earthquake data
        //mAdapter.clear();

        // If there is a valid list of {@link News}s, then add them to the adapter's
        // data set. This will trigger the ListView to update.
        if (news != null && !news.isEmpty()) {
            mAdapter.addAll(news);
        }
    }
    @Override
    public void onLoaderReset(Loader<List<News>> loader) {
        // Loader reset, so we can clear out our existing data.
        Log.i(LOG_TAG, "test: onLoaderReset() called...");
        mAdapter.clear();
    }
}

我现在获得的错误是我帖子的标题中的错误

这是我的傻瓜
