appium中的NoSuchMethodError

时间：2014-10-22 13:11:37

标签： java maven appium

我在设置第一个appium项目后得到了java.lang.NoSuchMethodError 代码很简单，它在这一行失败了：

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

跟踪是：

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.http.JsonHttpCommandCodec.encode(JsonHttpCommandCodec.java:197)
    at org.openqa.selenium.remote.HttpCommandExecutor.execute(HttpCommandExecutor.java:152)
    at org.openqa.selenium.remote.RemoteWebDriver.execute(RemoteWebDriver.java:572)

我的pom.xml是：

    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.11</version>

</dependencies>

我谷歌了，有人说我使用的是较旧的guava.jar，但是我发现了guava-15.0.jar并且发现Joiner.appendTo（StringBuilder，Iterable）存在，为什么它总是显示这个错误？< / p> 

@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);
  }

运行命令“mvn -U clean test”后，我也可以看到此错误

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

只有一个名为addContact的测试用例，为什么它一直显示Test run：2？通过调试，我发现它在运行这句“driver.quit（）”时发生，在删除此方法后，它显示了测试运行：1

依赖树是下面的列表，我没有看到任何关于MapJoiner的信息，除了guava-17.0，实际上我可以在这个jar文件中找到MapJoiner.appendTo（Stringbuilder，iterate＆lt;＆gt;）

您使用的是哪种版本的硒？

使用以下方式之一编辑pom.xml。

    <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>

对于上述依赖项，使用AndroidDriver（）代替AppiumDriver（）或使用以下内容与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>

这是硒和鸦片版本不匹配。两者的最新版本都可能导致这种错误。您可以在下面找到最新的匹配版本：

Sub sbCopyingAFileReadFromSheet()
Dim FSO
Dim sFile As String
Dim sSFolder As String
Dim sDFolder As String
'source file
sFile = Sheets("Main").Range("C26")
'source folder
SFolder = Sheets("Main").Range("c27")
'destination folder
sDFolder = Selection
'Create Object for File System
Set FSO = CreateObject("Scripting.FileSystemObject")
'Checking If File Is Located in the Source Folder
If Not FSO.FileExists(sSFolder & sFile) Then
    MsgBox "Specified File Not Found in Source Folder", vbInformation, "Not Found"
'Copying If the Same File is Not Located in the Destination Folder
ElseIf Not FSO.FileExists(sDFolder & sFile) Then
    FSO.CopyFile (sSFolder & sFile), (sSFolder & sDFolder), True
    MsgBox "Specified File Copied to Destination Folder Successfully", vbInformation, "Done!"
Else
    MsgBox "Specified File Already Exists In The Destination Folder", vbExclamation,"File Already Exists"
End If
End Sub

随时使用最新的匹配版本来编辑此答案。
