~/hack/nativescript/sample-Groceries$ echo $JAVA_HOME
/usr/lib64/jvm/java
~/hack/nativescript/sample-Groceries$ javac

  -g:none                      Generate no debugging info
  -h <directory>
        Specify where to place generated native header files
  --help, -help                Print a synopsis of standard options
  -implicit:{[none, class],[none, class]}
        Specify whether or not to generate class files for implicitly referenced files
  -J<flag>                     Pass <flag> directly to the runtime system
  --limit-modules <module>(,<module>)*
        Limit the universe of observable modules
  --module <module-name>, -m <module-name>
        Compile only the specified module, check timestamps
  --module-path <path>, -p <path>
        Specify where to find application modules
  --module-source-path <module-source-path>
        Specify where to find input source files for multiple modules
  -nowarn                      Generate no warnings
  -parameters
        Generate metadata for reflection on method parameters
  -proc:{[none, only],[none, only]}
        Control whether annotation processing and/or compilation is done.
  -processor <class1>[,<class2>,<class3>...]
        Names of the annotation processors to run; bypasses default discovery process
  --processor-module-path <path>
        Specify a module path where to find annotation processors
  --processor-path <path>, -processorpath <path>
        Specify where to find annotation processors
  -profile <profile>
        Check that API used is available in the specified profile
  --release <release>
        Compile for a specific VM version. Supported targets: 6, 7, 8, 9
  -s <directory>               Specify where to place generated source files
  -source <release>
        Provide source compatibility with specified release
  --source-path <path>, -sourcepath <path>
        Specify where to find input source files
  --system <jdk>|none          Override location of system modules
  -target <release>            Generate class files for specific VM version
  --upgrade-module-path <path>
        Override location of upgradeable modules
  -verbose                     Output messages about what the compiler is doing
  -version                     Version information

  -X                           Print a synopsis of nonstandard options

The message from the tns platform command is useless because it does not say what the error is.
