Joe Bowser commented on CB-11343:
---------------------------------
BTW: This is related to CB-11640, because check-reqs should not allow 1.7 to
install, but let JDK 8 and JDK 9 to be installed.
> Handle Java 9 after JEP 223

> Key: CB-11343
> URL: https://issues.apache.org/jira/browse/CB-11343
> Project: Apache Cordova
> Issue Type: Improvement
> Components: Android
> Affects Versions: 5.1.1
> Reporter: Andreas Kohn
> Assignee: Joe Bowser
>
> `cordova requirements android` fails on a system with Java 9(-ea) installed
> and accessible via PATH/JAVA_HOME:
> {code}
> $ cordova requirements android
> Requirements check results for android:
> Java JDK: not installed
> Cannot read property '1' of null
> Android SDK: installed
> Android target: installed
> android-17,android-18,android-19,android-21,android-22,android-23,android-N
> Gradle: installed
> Error: Some of requirements check failed
> $ echo $PATH
> /usr/lib64/qt-3.3/bin:/usr/lib64/ccache:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/andreas/.local/bin:/home/andreas/bin:/usr/java/jdk-9/bin:/home/andreas/modules/apache-maven/bin:/home/andreas/modules/apache-ant/bin:/home/andreas/modules/mongodb/bin:/home/andreas/modules/node/bin:/home/andreas/modules/android-sdk-linux/tools:/home/andreas/modules/android-sdk-linux/platform-tools
> $ which javac
> /usr/java/jdk-9/bin/javac
> $ echo $JAVA_HOME
> /usr/java/jdk-9
> $ javac -version
> javac 9-ea
> $ java -version
> java version "9-ea"
> Java(TM) SE Runtime Environment (build 9-ea+120)
> Java HotSpot(TM) 64-Bit Server VM (build 9-ea+120, mixed mode)
> {code}
> The exception is caused by the regular expression magic in check_reqs.js,
> `check_java` function:
> {code}
> var match = /javac ((?:\d+\.)+(?:\d+))/i.exec(output)[1];
> {code}
> (5.2.0-dev is slightly different, but has the same issue).
> I think the easiest fix here is to change the expression to this:
> {code}
> var match = /javac ((?:\d+\.)*(?:\d+))/i.exec(output)[1];
> {code}
