Question

因此，在尝试并验证所有路径，版本和建议后，Android的cordova要求仍然失败。它是在OSX 10.10.5和Android SDKs / Studio和cordova的全新安装。尝试了Apple推荐（导出JAVA_HOME = /usr/libexec/java_home -v 1.8）并使用相同的失败结果直接路径。验证了两个java / javac都在JDK路径的bin目录中。

在gitHub上挖掘cordova-android源代码的唯一方法是在check_reqs.js中，错误信息是：

Failed to run "javac -version", make sure that you have a JDK installed.

而不是目前的报道：

Failed to run "java -version", make sure that you have a JDK installed.

任何帮助非常感谢。罗布

Answer 1

所以有很多问题。 check_reqs.js是完成平台/环境检查的地方（app / platforms / android / cordova / lib /）。在第98行调用forgivingWhichSync（'javac'）返回非JDK链接（因为它使用的是Current，而不是CurrentJDK）： /System/Library/Frameworks/JavaVM.framework/Versions/A/Commands/javac

通过将/System/Library/Frameworks/JavaVM.framework/Versions/中的当前符号链接重新映射到CurrentJDK，修复了第一个问题：

lrwxr-xr-x  1 root  wheel   10 21 Jul 12:03 Current -> CurrentJDK
lrwxr-xr-x  1 root  wheel   59 21 Jul 12:06 CurrentJDK -> /Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents

下一个问题是测试javac的tryCommand方法存在问题。正确地说，javac -version返回stderr中的信息。问题（至少在OSX上）是第44行对child_process.exec的调用也返回错误信息：

Error: Command failed: /bin/sh -c javac -version
javac 1.8.0_102
javac: no source files
Usage: javac <options> <source files>
where possible options include:
  -g                         Generate all debugging info
  -g:none                    Generate no debugging info
  -g:{lines,vars,source}     Generate only some debugging info
  -nowarn                    Generate no warnings
  -verbose                   Output messages about what the compiler is doing
  -deprecation               Output source locations where deprecated APIs are     used
  -classpath <path>          Specify where to find user class files
  -cp <path>                 Specify where to find user class files
  -sourcepath <path>         Specify where to find input source files
  -bootclasspath <path>      Override location of bootstrap class files
  -extdirs <dirs>            Override location of installed extensions
  -endorseddirs <dirs>       Override location of endorsed standards path
  -d <directory>             Specify where to place generated class files
  -encoding <encoding>       Specify character encoding used by source files
  -source <release>          Provide source compatibility with specified release
  -target <release>          Generate class files for specific VM version
  -version                   Version information
  -help                      Print a synopsis of standard options
  -X                         Print a synopsis of nonstandard options
  -J<flag>                   Pass <flag> directly to the runtime system

如果err为非null，则处理对此child_process.exec的回调始终会触发错误： if（err）d.reject（new CordovaError（errMsg））; 将此更改为仅在未设置catchStderr标志时才触发此错误现在可以正确处理javac的测试： if（err＆amp;＆amp;！catchStderr）d.reject（new CordovaError（errMsg））;

现在成功：

sh-3.2# cordova requirements

不幸的是，当你使用cordova平台添加android时，需要为每个项目编辑check_reqs.js，但至少它现在可以找到所有内容。

Answer 2

当我在OSX上使用Cordova版本7和JDK 1.8u131进行安装时，一切都运行良好。无需更改或配置任何内容。可能旧版本的Cordova存在问题。

Cordova / Android没有在OSX和PATH / JAVA_HOME上找到JDK
