java - 执行 phonegap 命令 cordova build 时出错

Question

我正在执行命令“cordova build”(完成上述设置后，示例链接Phonegap The Command-Line Interface)。
但是 note.js 返回这个错误:

Generating config.xml from defaults for platform "android"
Preparing android project
Compiling app on platform "android" via command "cmd" /c
C:\Net\Phonegap\hello\platforms\android\cordova\build
Error: An error occurred while building the android project.Error executing "ant" debug -f "C:\Net\Phonegap\hello\platforms\android\build.xml"":
BUILD FAILED
C:\Net\templates\Phonegap\android-sdk\tools\ant\build.xml:601: The following error occurred while executing this line:
C:\Net\templates\Phonegap\android-sdk\tools\ant\build.xml:720: The following error occurred while executing this line:
C:\Net\templates\Phonegap\android-sdk\tools\ant\build.xml:734: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "C:\Program Files\Java\jre7"

我的config.xml

<widget id="com.example.hello" version="0.0.1">
<name>HelloWorld</name>
<description>
    A sample Apache Cordova application that responds to the deviceready event.

<preference name="WebViewBounce" value="true" />
<feature name="Device">
    <param name="android-package" value="org.apache.cordova.device.Device" />
</feature>

还有我的 AndroidManifest.xml

<manifest android:hardwareAccelerated="true" android:versionCode="1" android:versionName="0.0.1" android:windowSoftInputMode="adjustPan" package="com.example.hello" xmlns:android="http://schemas.android.com/apk/res/android">

<uses-permission android:name="android.permission.INTERNET" />
<application android:debuggable="true" android:hardwareAccelerated="true" android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:configChanges="orientation|keyboardHidden|keyboard|locale" android:label="@string/app_name" android:name="HelloWorld" android:theme="@android:style/Theme.Black.NoTitleBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>
<uses-sdk android:minSdkVersion="10" android:targetSdkVersion="19" />

看起来您目前已经安装了 Java 运行时环境 (JRE)。您需要 Java 开发工具包 (JDK)。你可以在 Oracle 得到它.您的路径似乎使用 %JAVA_HOME%\bin 正确设置。我相信一旦安装了 JDK，您的 %JAVA_HOME% 环境变量将更改为类似于:C:\Program Files\Java\jdk1.7.0_52。当然，版本号可能略有不同。
