maven 没有将 test/java 类编译到目标文件夹中

Question

我尝试通过 maven->clean 和 project->clean 清理我的项目，但没有奏效。我尝试在构建路径下显式更改我的输出文件夹，但不确定为 src/test/java 选择什么

我还在 pom.xml 中更新了我的 testng 插件

src/test/java 和 src/test/resources 的输出文件夹是 /target/classes

我得到 TestNG class not found in classpath 错误：

org.testng.TestNGException: 
Cannot find class in classpath: testclass file

之前这段代码运行良好。我只是尝试通过更改 maven 项目的工件 id 来重构项目，然后无法继续。

Answer 1

不确定这适用的范围有多广，但我在这方面取得了成功：

右键 > Java 构建路径 > 源 确保检查所有 4 个文件夹的 Include:(All) 和 Exclude:(None)

src/main/java

src/main/资源

src/test/java

src/test/resources

Answer 2

您需要添加 ma​​ven surefire 插件 来运行 testNG 类。如果您能够在没有此插件的情况下更早地运行测试，那将是一个奇迹。您必须在构建阶段添加以下插件才能开始。

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.20.1</version>
    <configuration>
      <includes>
        <include>Sample.java</include>
      </includes>
    </configuration>
  </plugin>

如果您不想手动包含测试，那么默认情况下，Surefire 插件将自动包含所有具有以下通配符模式的测试类：

"**/Test*.java"

"**/*Test.java"

"**/*Tests.java"

"**/*TestCase.java"

Answer 3

我认为你必须将非 maven 项目转换为 maven 项目

right click on project->Configure->Convert it to Maven

Answer 4

对我来说，问题是“跳过测试”复选框被选中。

RClick 项目 -> 运行方式 -> 运行配置 -> Maven 构建（选择您的构建配置） -> 取消选中跳过测试复选框

此复选框可防止 Maven 编译测试

如果您想编译测试，但不想在构建过程中执行它们，请在目标中添加 -DskipTests
