也许JAVA_HOME没有指向JDK

Question

我在制作phonegap的过程中遇到此错误

C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:601: The followin
g error occurred while executing this line:
C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:720: The followin
g error occurred while executing this line:
C:\Program Files (x86)\Android\android-sdk\tools\ant\build.xml:734: Unable to fi
nd 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\jre1.8.0_25"

我认为我已添加到Windows环境变量的系统变量的PATH问题。

• JAVA_HOME-> C：\\ Program Files \\ Java \\ jdk1.8.0_25; C：\\ Progra〜2 \\ Java \\ jdk1.8.0_25 \\ jre

Answer 1

当前设置为“ C：\\ Program Files \\ Java \\ jre1.8.0_25”

jre代表Java Runtime Environment，您需要jdk ，它是Java开发工具包。

因此， JAVA_HOME应该指向C:\\Program Files\\Java\\jdk1.8.0_25 ，在PATH系统变量中，您应该拥有C:\\Program Files\\Java\\jdk1.8.0_25\\bin 。

Answer 2

确保您使用的是Java SE SDK，而不是Java EE SDK，因为android无法识别第二个。
