我在linux上有一个maven项目。 直到上周才建成。 今天我收到以下错误
[ERROR] Failed to execute goal on project my-integration-service: Could not resolve
dependencies for project com.mycompany.myproj:my-integration-service:jar:0.0.1-SNAPSHOT:
Failed to collect dependencies for [org.springframework:spring-core:jar:4.0.4.RELEASE
(compile), org.springframework:spring-tx:jar:4.0.4.RELEASE (compile), ...]: No versions

我检查了我的settings.xml，在本地存储库中，我可以看到这个的很多版本...库2.2,2.4 ... 2.9.1
我还看到了文件M2_REPO / joda-time / joda-time / resolver-status.properties

我还运行了命令mvn -X archetype：按建议生成What could be causing 'error transferring file' in maven?

不太确定可能导致此错误的原因是什么？
使用Apache Maven 3.0.3（r1075438; 2011-02-28 12：31：09-0500）

您无权访问您的存储库。

这里最有可能的问题是您的凭据。你可能没有正确地提供它们。

#include<iostream>
#include<vector>
using namespace std;
int main()

int N;
cin>>N;
int edges[N][N];
for(int i=0;i<N;i++)

int ans=0;

}
}
`cout<<ans/16; `// i did this becoz i think that every quadrilateral will be counted 16 times by this code
更新V：\ Ecomm \ apache-maven-3.6.1 \ conf \ settings.xml
I had proxy issue

我使用了以下标志，它成功下载了所有内容。
System.out.println(Arrays.toString(priorityQueue.toArray()));
