Eclipse Jdk 1.8

Java 8 is officially available since a couple of days. It was released on March 18th this year. Yeah! But – Eclipse, the biggest and most popular Java IDE is a little bit behind the schedule (at least IMHO). There is no official Eclipse version for Java 8 right now!

How to set Eclipse to have the JRE library and / or JDK 1.8. First, to install a JDK for use anywhere in Eclipse, Click the Windows menu, then Preferences. In that window on the left, expand Java, then click on Install JREs. And enter the home directory of your JDK. The Eclipse OpenJ9 project source code can be built against multiple JDK levels starting with JDK8, so the question of support has a more complicated answer than at OpenJDK. Our community is committed to supporting JDK levels as long as they are supported at the OpenJDK open source project with a significant user base. The Java to run Eclipse can be specified in the eclipse.ini file (see Eclipse wiki: eclipse.ini - Specifying the JVM). Add the following two lines directly before the line -vmargs and adapt the path to your Java 11 or higher 64-bit Java VM installation directory:-vm C: Program Files AdoptOpenJDK jdk-14.0.2.12-openj9 bin javaw.exe. Install the plugins and restart eclipse. Now if you have JDK 1.8 on your computer and added it as an installed JRE you'd be able to view and use JavaSE-1.8 Or just download and use the latest eclipse. The Eclipse workbench provides a new dark theme which includes syntax highlighter settings for several programming languages. Paho provides open source implementations of open and standard messaging protocols that support current and emerging requirements of M2M integration with Web and Enterprise middleware and applications.

But there are two other thing: an up-to-date nightly build of the new Eclipse version Luna which will be released with Java 8 support and a patch for the current Eclipse version Kepler! Since it is sometimes (= always) hard to find the correct Eclipse version on eclipse dot org or anything useful at all, here is how to do it.

If you still use Eclipse Juno (4.2), you use an old version of Eclipse without Java 8 support and I strongly recommend to use a new version (as described below). If you cannot do that (or don’t want to do that) here is an old tutorial from me how to setup Java 8 in Eclipse Juno: http://tuhrig.de/java-8-in-eclipse-juno.

Kepler (4.3) is the current version of Eclipse. You can download it from http://www.eclipse.org/downloads. After you downloaded it, it will not have Java 8 support right out of the box! To add it, you have to install a feature patch:

  1. Download and install Java 8 (e.g. from Oracle JRE/JDK or OpenJDK)
  2. Add it to Eclipse:
  3. Install the feature patch via Help > Install New Software..:
    http://download.eclipse.org/eclipse/updates/4.3-P-builds/

You have to restart Eclipse during the installation and accept a license and click several next-buttons. But after you installed the feature patch, you have Java 8 support in Eclipse Kepler (4.3). Jiffy lube services prices. If you have problems with the installation process, download a new Eclipse Kepler version.

Eclipse Jdk 1.8 Downloads

Luna (4.4) is the upcoming version of Eclipse. It will be released this summer and it will contain Java 8 support. But you can already download some nightly builds of it which contains Java 8 support.

Eclipse

You can download Eclipse Luna here. Just make sure you download the correct build version, since not all builds have Java 8 support already! When you download the correct version, you can just run Eclipse and use the new Java 8 features (you also need to install Java 8, e.g. from Oracle JRE/JDK or OpenJDK).

By the way, some nightly builds still contain test errors. This is due to the fact that Eclipse Luna is still in development. But to play around with Java 8 or for a small project it should already be good enough.

To test your Eclipse IDE, here is a very simple Java 8 example:

2
4
publicstaticvoidmain(String[]args){
newThread(()->System.out.println('Hello Java 8!')).start();
}

If you have problems with Java 8 in Eclipse check your project settings. If your compliance level is not set to 1.8, you cannot use Java 8. And if you don’t even have the compliance level 1.8 then your Eclipse somehow doesn’t support Java 8 and something went wrong. In this case, get yourself a new Kepler version and install the feature patch or download an appropriate Luna build as described above.

Dear forum
I struggle since two hours trying to get a first Java 8 interface to run.
The Eclipse Luna IDE 4.4M6 states: Error on 'default' delete this token.
I also can not set the compiler level to 1.8..
Does anybody know why I can not choose a new compiler level?
I have linked the Installed JRE 1.8 and both got JRE 1.8 and JDK 1.8 installed.
Anyone?
Thank you and best regards
Dominik

Did you install the JDT feature patch? M6 does not by default come with
Java8 support.

I have a 4.4m6 build available which holds java8 support at
http://downloads.efxclipse.bestsolution.at/downloads/nightly/sdk/ it
holds many things so it might be appropriate for your needs so feel free
to use feature patches.

I builds themselves don't have any Java8 support yet! The download I
pointed to installs the feature patch available!
