對於commons-fileupload和commons-io的Maven依賴

Question

我想通過STS將commons-fileupload和commons-io庫添加到我的項目中。 當我試圖在我的pom.xml中添加依賴項並更新它時，我繼續收到以下所有版本的錯誤

Maven dependency problem
    ArtifactDescriptorException: Failed to read artifact descriptor for commons-fileupload:commons-fileupload:jar:1.1: 
    ArtifactResolutionException: Failure to transfer commons-fileupload:commons-fileupload:pom:1.1 from http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. 

    Original error: Could not transfer artifact commons-fileupload:commons-fileupload:pom:1.1 from/to central (http://repo1.maven.org/maven2): Connect times out

我試着從mvn查找：

http://mvnrepository.com/artifact/commons-io/commons-io/2.4
http://mvnrepository.com/artifact/commons-fileupload/commons-fileupload/1.2.2

我沒有其他庫的問題，特別是commons-logging。
我正在使用SpringSource Tool Suite版本：2.9.2.RELEASE用於我的Spring項目。

Answer 1

首先刪除您的本地存儲庫（可能只是commons-io etc文件夾），然后在以下URL下僅檢查Maven Central：

http://search.maven.org/

在哪里找到所需的依賴項：

<dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId>commons-fileupload</artifactId>
    <version>1.2.2</version>
</dependency>

<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.4</version>
</dependency>
