any solution for this?
Gradle sync failed: Could not run JVM from the selected JDK.
Please ensure JDK installation is valid and compatible with the current OS (macOS 10.13.4, x86_64).
If you are using embedded JDK, please make sure to download Android Studio bundle compatible
with the current OS. For example, for x86 systems please choose a 32 bits download option. (60 ms)
For all the people saying they still don't see Java in their system preferences, what worked for me was installing the ME SDK, located here on Oracle's site:
I messed around with this forever, tried to install previous versions of SDK/JDK all without it working. What DID finally work is installing the SDK for ME, located here: https://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javame-419430.html#sun_java_me_sdk-3.0-rr-mac-JPR
could you teach me how to undo the installation?
I followed ur steps, but I wanna know how to undo it just in case I had to ._.
is it gonna ruin my MacBook Air.. it's kinda scary and I have no experience with this what so ever. thanks for the video, it was fun following u
UNABLE TO EXPORT JAVA INTO JAVA_HOME despite doing all the steps..
I already had .bash_profile on the list however, it was added by anaconda installer . The message displayed on the editor said : # added by Anaconda3 4.4.0 installer
I continued typing the command as instructed : export JAVA_HOME=$(/usr/libexec/java_home)
saved it, and a pop up message came out said that I have no right to write on the .bash_profile, since I didn't own it, it gave me an option to make a duplicate, and I did. Then I paste the instruction in the duplicate version, save it, and another pop up came out, said that saving using "." extension (.bash_profile) will cause the file to be hidden. So first I saved without "."extension, and close everything, reopen the terminal writhe the echo $JAVA_HOME press enter, and I didn't get the location, only an empty space as it hasn't been created yet. Then I tried to ignore the "." extension naming method, still it yield nothing....
Oh, I also tried to create .bash_profile using the instructed command : touch .bash_profile
however, it wasn't allowed (touch: .bash_profile: Permission denied)
Anyone, could you please help me to solve the problem....I would highly appreciate it..
Thanks in advance
Hello. New to programming and am in the process of learning Java. Quite unfamiliar with the Terminal (I'm mostly working on a PC). Your video was *much* more helpful than most of those I saw first and really helped me understand what all these random terminal commands mean. Chapeau sir and thank you
Cool. One of the best tutorials I'd ever watched. Your step-by-step approach is Very helpful for people like us (I guess we are your targeted audience) who have little understanding of using terminal and installing apps like Java, etc. Thank you heaps.
One question though, following everything through successfully to 14:30 when I open my .bash_profie I have already an entry there:
(I use MAMP as my dev server)
Using echo$JAVA_HOME command in terminal gives me: JAVA_HOME: Undefined variable
I tried to look up some explanation on the internet but to no avail.
My name is Mohit Jain. I am writing a blog for Java “https://thecodecounty.com” (just started).
I need your permission to use your videos where you explain about setting up environment variables for Mac, Windows and Ubuntu.
Do I have your permission to use these?
Thank you so much! I had a hard time looking for decent videos on installing java on Mac. This is by far the one with the clearest instructions. I successfully installed Java and Netbeans IDE with the help of your tutorials : )
hi bro I have Java JDK 10 in my Mac book air.when I'm trying to run the web project eclipse is saying that ERROR: JVM Not Found , Fatal Exception Occurred.i'm unable to. solve this error please help me.i have tried uninstalling and reinstalling eclipse, java and apache but it's not working please suggest me how to solve this issue
my .bash_profile is already showing
and echo $JAVA_HOME tells me that it is an Undefined Variable
so obviously something wrong with people who use MAMP as their dev server
Couldn't find any solution but NETBEANS IDE is out of reach because of that.
