java - 为什么Java找不到包？

问题描述

我尝试运行从GitHub 获得的 Java 代码 DictionaryPC 的 compile.sh。 每次运行它时，我都会收到如下所示的错误。但是据称丢失的 .class 文件确实以文件夹 ../com/hughes/android/ 的形式存在

compile.sh 中的路径设置正确。

../Dictionary/src/com/hughes/android/dictionary/engine/Dictionary.java:17: error: package android.content does not exist
import android.content.ContentResolver;
                      ^
../Dictionary/src/com/hughes/android/dictionary/engine/Dictionary.java:18: error: package android.support.v4.provider does not exist
import android.support.v4.provider.DocumentFile;
                                  ^
../Dictionary/src/com/hughes/android/dictionary/engine/Dictionary.java:197: error: cannot find symbol
    private static DictionaryInfo getErrorDictionaryInfo(final DocumentFile file) {
                                                               ^
