jenkins+maven+testng时，报：[TestNGClassFinder] Warning: Can't link and determine methods of class

报错原因

由于maven执行测试类时无法判断要执行哪些case

解决办法

1. 创建xml文件，示例：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="flight">
    <test name="example" preserve-order="true">
        <classes>
            <class name="com.elong.android.flight.test.AirTest">
                <methods>
                    <include name="test"></include>
                </methods>
              <!--   <groups>
                    <run>
                        <include name="group1"></include>
                    </run>
                </groups> -->
            </class>
        </classes>
    </test>

</suite>

2 在maven-compiler-plugin和maven-surefire-plugin插件引入testng运行策略xml文件，如下示例

  <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.3</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                    <compilerArguments> 
                      <extdirs>libs/</extdirs> 
                    </compilerArguments> 
                    <suiteXmlFiles>
                      <suiteXmlFile>testflight.xml</suiteXmlFile> 
                    </suiteXmlFiles>
                </configuration>
        </plugin>
        <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.19.1</version>
                <configuration>
                    <suiteXmlFiles>
                      <suiteXmlFile>testflight.xml</suiteXmlFile> 
                    </suiteXmlFiles>
                </configuration>
        </plugin>

        </plugins>
    </build>
