Java &引用；mvn测试“；在控制台中给出不同的错误

我一直面临这三个错误：

java:[8,40]错误：找不到符号

Users.java:[5,25]错误：包com.project.tests不存在

找不到侦听器类

我转到这些行，发现行8,40有此错误，因为它在这一行找不到变量（符号）。对于第二个错误，我转到该行，它是

import com.project.tests.Repo

在源文件夹
src/test/java
中有两个包
import com.project.tests
，在
src/main/java
中有
import com.project.live
。因此，它可以找到
import com.project.live
，但不能找到
import com.project.tests
和
com.project.tests.Repo位于包
导入com.project.tests
中，这就是它给出错误的原因。

在阅读stackoverflow.com和其他论坛上的不同帖子时，我发现前两个错误可以通过将
maven compiler plugin
更新为
Version3.1
并将
testng
更新为最新版本来修复。昨天我做了更改并进行了测试，所以两个错误都被删除了，它开始出现#3错误。
但是今天当我进行
mvn测试时，接着是
mvn clean
，它有时同时出现错误1和2，有时单独出现错误3。
我不明白发生了什么。为了摆脱这个问题，我删除了
.m2
，并使用
mvn安装重新获得它
，但没有改变，它的行为一直很奇怪。
我将
pom.xml
粘贴到下面：
