See Java is correctly installed

$ java -version

#2

Cordova (or Android tooling) only works with JDK(1.)8, not 9 or 10. Install that, then it will work.


#3

do you mean JDK version 8 ?


#4

As far as i know… Java latest release is still at 8 (shit i was horribly outdated)

Your JAVA_HOME is invalid: C:\Program Files\Java\jdk-10;%JAVA_HOME%\bin;

Actually your issue is most likely because of undefined JAVA_HOME in your environmental variable

Follow this instructions
https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html


#5

JAVA_HOME is a valid directory i have already checked


#7

Same error after installing the JAVA (1.)8 version

But now you are running a Java version that could work.

What does ionic cordova requirements say?

#10

Fix this.

Best also install a standalone gradle from gradle.org/install


#11

i have installed gradle (4.4) but still facing error with JAVA_HOME please help me out

$ gradle -v

ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk1.8.0_161;C:\Program Files\Java\jdk1.8.0_161\bin

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

Java is also installed :-

$ java -version
java version "1.8.0_161"
Java™ SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot™ 64-Bit Server VM (build 25.161-b12, mixed mode)

i am also attaching the JAVA_HOME directory location.


#12

I see a list of directories set as JAVA_HOME. Maybe it only wants one?


#13

so which one shall i remove?


#14

You have 2 options. Try them and let us know which one worked.


#15

both doesnt worked for me :frowning:

$ gradle -v

ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk1.8.0_161\bin

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

$ gradle -v

ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk1.8.0_161\bin

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.


#16

You posted the same thing twice.
You should probably test both paths, not the same one twice.


#17

I’ve never used Windows, so can’t be more specific, but EPERM would seem to indicate that whatever user you are running the build as does not have write access to the build folder of the project.


#19

now opening app on android after installing shows

Application Error

The connection to the server was unsuccessful. (file://android_asset/www/index.html)


#20

try ionic cordova build android and see what output it gives
