问题:

i got java.lang.NoSuchMethodError after setting up my first appium project the code is simple, it fails at this line:

  driver = new AppiumDriver(new URL("http://x.x.x.x:4723/wd/hub"), capabilities);

The trace is:

java.lang.NoSuchMethodError: com.google.common.base.Joiner$MapJoiner.appendTo(Ljava/lang/StringBuilder;Ljava/lang/Iterable;)Ljava/lang/StringBuilder;
    at com.google.common.net.MediaType.toString(MediaType.java:674)

    at org.openqa.selenium.remote.HttpCommandExecutor.execute(HttpCommandExecutor.java:152)
    at org.openqa.selenium.remote.RemoteWebDriver.execute(RemoteWebDriver.java:572)

my pom.xml is:

i've google it, and some say that i use an older guava.jar, but i decomplie guava-15.0.jar and find the Joiner.appendTo(StringBuilder, Iterable) exist, why it always showing this error?

@Before
  public void setUp() throws Exception {
    // set up appium
    final File classpathRoot = new File(System.getProperty("user.dir"));
    final File appDir = new File(classpathRoot, "../../../apps/ContactManager");
    final File app = new File(appDir, "ContactManager.apk");
    final DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
    capabilities.setCapability("platformName", "Android");
    capabilities.setCapability("deviceName", "Android Emulator");
    capabilities.setCapability("platformVersion", "4.4");
    capabilities.setCapability("app", app.getAbsolutePath());
    capabilities.setCapability("appPackage",
        "com.example.android.contactmanager");
    capabilities.setCapability("appActivity", ".ContactManager");
    driver = new AndroidDriver(new URL("http://x.x.x.x:4723/wd/hub"),
        capabilities);
  }

also after running command "mvn -U clean test", i can see this error

Tests in error:        
addContact(com.saucelabs.appium.AndroidContactsTest):com.google.common.base.Joiner$MapJoiner.appendTo(Ljava/lang/StringBuilder;Ljava/lang/Iterable;)Ljava/lang/StringBuilder;
addContact(com.saucelabs.appium.AndroidContactsTest)
Tests run: 2, Failures: 0, Errors: 2, Skipped: 0

There's only one test case whose name is addContact, why it keep showing Test run: 2? through debugging, i found it happens when running this sentence "driver.quit()", after removeing this method, it shows Test run: 1

The dependency tree is list below, i don't see anything about MapJoiner except guava-17.0, actually i can find MapJoiner.appendTo(Stringbuilder, iterate<>) in this jar file

回答1:

Which version of selenium are you using ?

Edit your pom.xml in one of the following ways..

    <dependency>
        <groupId>io.appium</groupId>
        <artifactId>java-client</artifactId>
        <version>2.0.0</version>
    </dependency>

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>LATEST</version>
    </dependency>

For the above dependency use AndroidDriver() in place of AppiumDriver() or use the following with AppiumDriver()

    <dependency>
        <groupId>io.appium</groupId>
        <artifactId>java-client</artifactId>
        <version>1.5.0</version>
    </dependency>

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>2.42.2</version>
    </dependency>

Cheers



回答2:

This is selenium and appium versions mismatch. Even latest versions of both can result in such an error. You can find latest matching versions below:

'io.appium:java-client:5.0.1'
'org.seleniumhq.selenium:selenium-java:3.4.0'

Feel free to edit this answer with newest matching versions.
