I run the windows 10 64 bit version of Eclipse. The first time I log onto Eclipse it works just fine (though I haven't fun any code yet, so I'm not sure if that works) but upon closing and reopening Eclipse it says, "Version 1.8.0_301 of the JVM is not suitable for this product: version 11 or greater is required." and immediately quits. I have downloaded jdk 16 and installed it. Redownloading Eclipse fixes it until I close it again. How can I fix this? I am a new Java programmer and am not experienced with any of this.
You should have a folder like ths: C:\Program Files\Java. In there, there should be a folder named 1.8.0_301. Delete this folder and reinstall java.
I had the same problem, this solved it for me...
First of all I suggest you check the version of your eclispe IDE. You may have downloaded a version that doesn't supprot your installed jdk.
This link should provide you with the suitable jdk version for every eclipse version.

I hope I helped you a bit.
Cheers!
I had this problem with Java version 1.8.0_351.
In the program management settings of Windows I removed Java 8. After that, my Eclipse installation worked fine.

I upgraded to the newest Mac Pro running Big Sur (11.4) from my 12 year old Mac Pro running Mojave (10.14.6). The old version of Eclipse was version was Kepler service release 2. When I installed the Mac and restored from backup, Eclipse flat out would not run, so I deleted it and downloaded and installed the latest version 2021-03 (4.19.0). I also updated JAVA SE to version 16.0.1 from Java version SE 7.
When I tried to run/compile a previous working project, I get:
I then decided to update the libraries found in the Java Build Path properties to the latest I could find:
to see if that made any difference. It didn't. I'm probably missing something very basic but I don't know what, since I use Eclipse only rarely.
I decided to go down the rabbit hole and download the missing jars in the error log, one after another. It just kept getting deeper and deeper with no end in sight. Just didn't quite pass the smell test.
Hmmm. I originally downloaded eclipse from the main elcipse.org page and went to the downloads button and installed it. Turns out the eclipse directory was only 21.2 MB. Plugin directory was basically empty. Hmmm.
I stumbled on the download file eclipse-SDK-4.19-macosx-cocoa-x86_64.dmg after looking for a SWT download. This file was the eclipse version that was 295.4MB in size. Double hmmm. So I ran it. Needless to say I was startled when my project compiled and ran right off the bat. Gee, thanks eclipse. Can you make it any more difficult for your Mac users? Anyway after a wasted day of head banging... problem solved.
I am reading the JavaEE first cup, and I needs JDK8+, my version is older, so I upgraded my java, Configure the System Path, Install so on, I successfully run java -version in command prompt and it recognizes me that I've installed successfully, but when I start my NetBeans, It can't find Java! Not only that, but also my Eclipse neon can't find java! I check the eclipse.ini, maybe it just need a JDK 8. So I just wonder, how can I make my NetBeans found my Java?
I am new to netbeans,so I resort to configuration in eclipse.ini,I try to add “--ALL"like script,I doesn't work anyway!Thank to my patience,I notice some jdk1.8required
property,I am completely rush to my deadline,so I avoid to this problem,and got 1.8，but thanks a lot if you recommend eclipse IDE lastest version which can work well with JDK 10 without any modification in ini file!
I have been around 4 hours trying to install the Google Plugin for Eclipse Luna. I followed every step of the installing guide but when i finished the Google Logo for starting a new project didnt appear as it should:
As you can see even though i have the plugins installed i cant see the icon or start a new web project.
My operating sysyem is OSx Yosemite. I tried updating to Java 8 and JDK 8 (and 7) and deleting all the files as this question recommends. Also deleted and "reinstalled" eclipse and the plugin a lot of times but didn't workout.
Anybody with the same problem? Thanks a lot.
I had the exact same problem on my new MacBook. I had to install JDK 7. I downloaded and installed the Mac OS X x64 version of 7u75 from here:
JDK 7 Downloads
After it installs make sure it's the system default by executing the following from the Terminal:
/usr/libexec/java_home
If it looks good to go then just restart eclipse and you should be good to go.
I suggest you even to delete your Eclipse_Luna:
Re-install your Eclipse and then install the GAE-plugin again.
Remember to re-start your Eclipse after you've successfully install the GAE-plugin for Eclipse_Luna.
I faced the same issue.
I installed JDK 1.7 and used 1.7 jre for eclipse as mapped and downloaded the eclpise plugin AND restarted and it worked fine.
I'm using Eclipse to program Android applications, and when I opened the program yesterday, it popped up an error saying I need to install JRE - I've downloaded the JRE and installed it - when during the installation I got a message saying that the JAVA version I have on the computer (Version 7) is too old for the JRE (Version 8), and that I need to update the JAVA also.
I did so, and then opened up the Eclipse again - And all of the projects,that before worked great, are now full with errors.
I tried installing all of the SDK updates - didn't work, also tried uninstalling Eclipse and re-install it - also didn't work.
The errors I get are: "XXX cannot be resolved to a type" - in amost every single line in the project.
How do I fix it??
Thank you!!
android development tool(adt) are install.. and all update SDK and then import an old program.. Ithink then work.
I would suggest to check that your java build path is functioning properly. This kind of error for me usually means that eclipse cannot find the JRE installation.
Form eclipse you can go to Project->Properties and check for any errors there. Any inconsistency there would cause all your projects to fail.
First of all, you need the JDK installation, not JRE. Second, Android currently supports up to Java v7, which means you'll need to get JDK v7 from here. Make sure you download the correct 32-bit or 64-bit JDK version for your operating system.
Also, ensure your Android SDK and Android Development Tools (ADT) are on the same released version. Different versions of Android SDK and ADT can lead to many unforseen problems.
I'm trying to get started with Eclipse/Java/Scala on a MacBook. The installed JDK was 1.5. The SDT plugin for Scala requires 1.6 which was included in an OS update, but I also manually installed a package from Apple to update 1.6.
The problem is that I cannot run anything from Eclipse. I always get the following error:
An internal error occurred during: "Launching TestFooBasicTest".
Could not initialize class com.ibm.icu.impl.JavaTimeZone
I also tried to use the old 1.5 version, but to no avail.
What is going wrong here?
I had the same problem trying to run a scala program with Ubuntu 10.4 and stock eclipse (Galileo 3.5.2) and java (java-6-openJdk ) - and the scala pluging downloaded from scala site, of course. I fixed it by manually changing /usr/lib/eclipse/plugins/com.ibm.icu_4.0.1.v20100125.jar as suggested in this thread (btw I discovered that Emacs can change a jar file in place: nice):
http://www.eclipse.org/forums/index.php?t=msg&goto=488654
It's caused by ubuntu openjdk package with broken symbol links for TimeZone configuration. The best solution from forum thread is,
Reinstalling tzdata-java was the fix for me:
sudo apt-get --reinstall install tzdata-java
The problem is:
An internal error occurred during: "Launching TestFooBasicTest". Could not initialize class com.ibm.icu.impl.JavaTimeZone
A quick google search reveals that this class belongs to the IBM Globalization package ICU. http://www-01.ibm.com/software/globalization/icu/index.jsp
A guess would be that this is a package used internally by Scala that you have not installed properly, causing Scala startup to fail.
Make sure that you set java 1.6 in the run configuration (Run/Run configurations).
Did you upgrade to Snow Leopard? Are you using the Eclipse SWT/Carbon or the Eclipse SWT/Cocoa? I was seeing some strangeness with Eclipse after I upgraded to SL. Switching to the Eclipse SWT/Cocoa from Eclipse SWT/Carbon helped. Also restoring my 1.5 VM, which the SL install removes in a sneaky way(by deleting and leaving the symbolic link pointing to 1.6), helped me fix several issues with Java code that had natives(i.e. usb-serial port code).
Check what are the JVMs that Eclipse is aware of and where they are located (Preferences -> Java -> Installed JRE), and also check the run/debug configuration of your programs. By default, Eclipse knows about the JRE that was used to launch itself, and other JREs that you add manually. However, if you upgrade some components and the JREs changed, Eclipse can get "confused" about them.
I had this same issue with Eclipse on Windows. I tried a number of different things including a new hello world program in a new workspace. I finally got this to work by pointing Eclipse to a different JRE to execute with. I know that Apple provides the JRE for Mac, but it does seem like this issue is related to Eclipse having trouble with the JRE used to run Eclipse itself. See here for configuring which VM Eclipse executes with.
