maven surefire验证java.lang.ClassNotFoundException

Question

当我尝试为我的java spring项目运行maven的验证生命周期时,我遇到了一个奇怪的错误.请注意,它可以很好地使用,mvn spring-boot:run但是当我运行mvn clean verify它时会爆炸:

$mvn clean verify -Dsurefire.skip=true -X
...
Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.209 sec <<< FAILURE! - in com.fitforger.FitForgerBackendApplicationTests
    initializationError(com.fitforger.FitForgerBackendApplicationTests)  Time elapsed: 0.005 sec  <<< ERROR!
    java.lang.NoClassDefFoundError: com/fitforger/model/GymRat
    Caused by: java.lang.ClassNotFoundException: com.fitforger.model.GymRat

我能提供哪些相关信息？请参阅下面的一些初始背景.

Answer 1

通过以下方式解决OP问题,

这看起来与您所面临的相似.你能试试吗？

<plugin>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-maven-plugin</artifactId>
   <configuration>
        <classifier>exec</classifier>
   </configuration>
 </plugin>

Answer 2

对我来说，增加additionalClasspathElements了窍门（来源）：

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-failsafe-plugin</artifactId>
        <configuration>
            <additionalClasspathElements>
                <additionalClasspathElement>${basedir}/target/classes</additionalClasspathElement>
            </additionalClasspathElements>
            <includes>
                <include>**/*IT.java</include>
            </includes>
        </configuration>
        <executions>
            <execution>
                <goals>
                    <goal>integration-test</goal>
                    <goal>verify</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
