Question

我的项目无法解析com.twitter：hbc-core：2.2.0依赖性。您可以在下面看到pom.xml文件。我尝试重新导入所有Maven项目，并且发现依赖项位于https://search.maven.org/artifact/com.twitter/hbc-core/2.2.0/jar的存储库中。使用的中央存储库是https://repo.maven.apache.org/maven2。这些类无法导入，并且alt + enter不能提供有意义的导入。

最小，完整，可验证的示例：

import com.twitter.hbc.core.endpoint.StatusesFilterEndpoint;

public class TwitterProducer {


    public static  void main(String[] args){
        StatusesFilterEndpoint hosebirdEndpoint = new StatusesFilterEndpoint();
    }
}

我在这里可能会想念什么？

基于注释中的交流，看来Maven下载到本地class Solution: def widthOfBinaryTree(self, root): # table contains the first col_index for each level first_col_index_table = {} self.max_width = 0 def DFS(node, depth, col_index): if node is None: return # if the entry is empty, set the value if depth not in first_col_index_table: first_col_index_table[depth] = col_index self.max_width = max(self.max_width, col_index - first_col_index_table[depth] + 1) # Preorder DFS, with the priority on the left child DFS(node.left, depth+1, 2*col_index) DFS(node.right, depth+1, 2*col_index + 1) DFS(root, 0, 0) return self.max_width文件夹中的某些依赖项已损坏。

通过删除/重新命名此文件夹来强制Maven重新下载它们已解决了问题。
