无法执行目标 org.codehaus.mojo:exec-maven-plugin:1.6.0:java

Question

我正在尝试通过在Maven Run Configurations 中使用以下命令使用 pom.xml 文件执行 testNG 主类。

exec:java -Dexec.mainClass=com.selenium.controls.TestNGMainClass

在这里，我使用的是Java 8。

但我收到以下错误。

请帮我解决这个问题。

假设您在 src/test/java 中有一个 Main.java

在你的 pom.xml 中添加这个

 <build>
            <plugins>
                <plugin>
                    <groupId>org.codehaus.mojo</groupId>
                    <artifactId>exec-maven-plugin</artifactId>
                    <version>1.6.0</version>
                    <configuration>
                        <classpathScope>test</classpathScope>
                        <mainClass>Main</mainClass>
                    </configuration>
                    <executions>
                        <execution>
                            <id>run-selenium</id>
                            <phase>integration-test</phase>
                            <goals><goal>java</goal></goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>

并通过以下方式运行它：

mvn clean install 或者 mvn exec:java
