Maven項目是通過Eclipse Update Project而不是pom.xml進行編譯的？

Question

我是Maven的新手，每次必須通過pom.xml或testng.xml運行Maven項目之前都要更新我的Maven項目。

每當我在Maven清理，更新項目然后進行Maven測試之后運行項目時，它都可以正常工作。 但是，如果我嘗試直接運行clean並進行測試，則會出現類路徑錯誤。 干凈的目標是清除目標，然后maven無法編譯，但是，如果我通過Eclipse更新項目，則不會發生問題。 嘗試更新testng和maven surefire插件。 以下是我的pom

Answer 1

在您的pom.xml您具有以下部分：

<dependency>
    <groupId>org.testng</groupId>
    <artifactId>testng</artifactId>
    <version>6.13.1</version>
    <scope>test</scope>
</dependency> 

您必須更改scope以進行編譯，因此它將

<dependency>
    <groupId>org.testng</groupId>
    <artifactId>testng</artifactId>
    <version>6.13.1</version>
    <scope>compile</scope>
</dependency>
