testNG jar包启动找不到org.testng.TestNG

主要是因为打包时依赖的jar包没有打入，网上有很多需要将对应的jar单独拷贝出来然后通过classpath引用启动，但是感觉这个就是个无底洞。拷贝了这么多个包最后还是说找不到ObjectId

 

 

 启动命令是（需要cd到这个文件夹下面）

java -classpath test.jar;testng-6.9.4.jar;jcommander-1.64.jar;extentreports-3.0.3.jar;freemarker-2.3.23.jar org.testng.TestNG system_pro.xml

执行结果：

C:\Users\admin\Desktop\test>java -classpath test.jar;testng-6.9.4.jar;jcommander-1.64.jar;extentreports-3.0.3.jar;freemarker-2.3.23.jar org.testng.TestNG system_pro.xml
[TestNG] Running:
  C:\Users\admin\Desktop\test\system_pro.xml

不知道哪里出了问题。。。。

另一种解决方法：

maven使用打包插件将依赖的jar包一起打包，pom.xml添加插件：

<build>
        <plugins>
            <plugin>
                <!-- 指定项目编译时的java版本和编码方式 -->
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.7.0</version>
                <configuration>
                    <target>1.8</target>
                    <source>1.8</source>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>3.1.0</version>
                <configuration>
                    <archive>
                        <manifest>
                            <mainClass>com.genergy.Excel2Test</mainClass> <!-- 指定入口类路径 -->
                        </manifest>
                    </archive>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef> <!-- jar包后缀，生成的jar包形式为：project-1.0-SNAPSHOT-jar-with-dependencies.jar -->
                    </descriptorRefs>
                </configuration>
                <!-- 添加此项后，可直接使用mvn package | mvn install -->
                <!-- 不添加此项，需直接使用mvn package assembly:single -->
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

通过mvn package 打好包之后，将需要执行

这里需要将测试的xml拷贝到和jar包一个路径

 

 然后执行

java -classpath jar包名 org.testng.TestNG xml名

如：
java -classpath genergy-api-test-1.0-SNAPSHOT-jar-with-dependencies.jar org.testng.TestNG system_pro.xml

 

最后生成测试报告在：
