Error: Failed To Run "javac -version", Make Sure That You Have A JDK Installed

Error: Failed to run 'javac -version', make sure that you have a JDK installed. You can get it from: http://www.oracle.com/technetwork/java/javase/downloads. Your JAVA_HOME

Solution 1:

Search for "edit environment variables" in start. and under user variables add a new variable with name "JAVA_HOME" and value with path_to_jdk_bin.

like this

Now under system variables, the path variable should contain(add if not added) the entry %JAVA_HOME%.

Like this

Solution 2:

Firstly make sure you don't have multiple java versions installed

Once you're done with that open Environment Variables tab under My computers

Create a new user variable and name it PATH

Set the user variable value as C:\Program Files\Java\jdk1.8.0_151\bin(may change depending on where you have installed java)

open cmd type javac

This should be enough to make it work

Solution 3:

I've been trying to figure this out and just found a solution I haven't seen elsewhere.

I noticed I had a second version of Java installed in my Program Files (x86) directory.

Pointing the variables to that location instead, ie C:\Program Files (x86)\Java\jdk1.8.0_131 and now everything works fine.

Solution 4:

Try This:

In VS, open Tools menu and select Options.

In Tools for Apache Cordova select Environment Variable Overrides .

Select JAVA_HOME checkbox and browse for JDK directory.
