maven没有将test / java类编译到目标文件夹中

Question

I tried cleaning my project through maven->clean and project->clean but it didnot work. I tried changing my output folders explicitly under build path but not sure what to select for src/test/java

I also updated my testng plugin in pom.xml

pom.xml

</project>

Output folders for src/test/java and src/test/resources is /target/classes

and I am getting TestNG class not found in classpath error :

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

Earlier this code was working fine. I just tried refractoring the project by changing artifact id of maven project and from then not able to proceed.

Answer 1

You need to add maven surefire plugin to run testNG classes. It's a miracle if you were able to run the tests earlier without this plugin. You have to add below plugin in the build phase to get going.

  <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>

If you don't want to include the tests manually then by default, the Surefire Plugin will automatically include all test classes with the following wildcard patterns:

"**/Test*.java"

"**/*Test.java"

"**/*Tests.java"

"**/*TestCase.java"

Answer 2

Not sure how widely this applies, but I had success with this:

Right click > Java build path > Source Make sure Include:(All) and Exclude:(None) is checked for all 4 folders

src/main/java

src/main/resources

src/test/java

src/test/resources

Answer 3

我认为您必须将非Maven项目转换为Maven项目

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

Answer 4

The issue for me was that the "Skip Tests" checkbox was checked.

RClick project -> Run As -> Run Configurations -> Maven Build (select your build configuration) -> Uncheck Skip Tests checkbox

This checkbox prevents Maven from compiling tests

If you want to compile the tests, but don't want to execute them during build process, add -DskipTests in Goals
