Question

我有一个maven项目，在运行maven安装时会返回以下堆栈跟踪：

[INFO] ------------------------------------------------------------------------

我尝试过更新项目并强制更新快照和发行版，但是似乎没有任何效果。

下面是我的pom.xml文件：

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

我在做什么错？以上错误是什么意思？

Answer 1

尝试以下选项：

确保已设置Java 8。例如，在eclipse中，在运行配置下检查jre指向的位置。如果未指向Java 8，则将其指向Java 8。
如果第1步不起作用，请删除your.m2 / repository文件夹并进行全新安装

Answer 2

似乎您刚刚下载了一个损坏的文件。删除.m2存储库目录并更新Maven项目将解决该问题。
