I just read How to have Eclipse use JDK8 to compile a project?
What i added jdk8 to eclipse as,
From the answers of How to have Eclipse use JDK8 to compile a project?
I tried to Update the JDT/Core, JDT/UI bundles from http://dist.springsource.com/snapshot/TOOLS/java8/e43
But it shows error as,
"Eclipse Java Development Tools Patch for Java 8 Support (BETA)" is not applicable to the current configuration and will not be installed.
"Eclipse Plug-in Development Environment Patch for Java 8 Support (BETA)" is not applicable to the current configuration and will not be installed.
How Can i fix it ?
I can say that Java 1.8 does in fact work with Eclipse Luna ( the beta version released around March 17, 2014) or later. I tried it and it was good.
Also, I noticed that in the Eclipse Marketplace, there are now plugins to install functionality into Kepler to support JDK1.8. I haven't tried the plugin myself though.
This is a old topic but I just wanted to point out that I have searched enough to find that Indigo version can't be updated to S.E 1.8 here the link which is given on eclipse website to update the Execution Environment but if you try it will throw error for Indigo.
Here is the link where the Information about execution environment is given.
This shows the step by step to update Execution environment.
I have tried to update Execution environment and I got the same error.

*Due to some project requirements I "have" to use eclipse 4.18 (2020-12) which uses Java 11 by default and is mandatory to start.
But my entire project is/was written in Java 1.7 earlier. Now , in my mac i have both java 1.8 and 11 installed also my eclipse settings are such shown below.
I have made sure removed all java 11 references in my eclipse and made the project and workspace configure to take the 1.8 jdk and run at 1.7 compiler level.*
but when i run ,project -->clean-->build, i run into the JaxB missing in java 11 ( in java 11 JAXB was removed and my project uses jaxB extensively) This is known.
So i am wondering what am i missing that my projects are still building my project with java 11 and not java 1.7 (using jdk 1.8 configured).
Please help.. stuck on this since some days.

If Eclipse itself is being run with Java 11, and you have a plug-in installed that has not been properly update to work under Java 11, as it appears, you will need an updated version of that plug-in. Update to the latest "oracle design studio", and if you still see this problem, contact Oracle support.
The latest Eclipse may require Java 11 to run, but it's simple to set up Eclipse projects that use older Java versions. Don't mess with the Java version it uses to start up, as long as that is a proper Java 11 version.
As one commenter mentions, you'll have to have a particular Java distribution configured in "Installed JREs->Execution Environments", and then you'll have to have the project configured to use that Java version symbol, like "JavaSE-1.7".
Can anybody tell me what the state of the Eclipse plugin for Gluon-Mobile is? It cannot be installed from the Eclipse marketplace anymore for the more recent Eclipse versions although the text states that it is compatible with the latest versions. Currently the marketplace is showing more than 80 failed installation attempts within the last 7 days.
The Gluon plugin for Eclipse works with Eclipse Version: 2019-03 (4.11.0) with the fix:

I am new to the team city as it is being used in our development environment and I have gone through its official website and to know more about it , but now my query is that I am stuck up in an very odd situation that is my project is in java and it uses jdk 1.5 and ant 1.5 now due to certain restrictions i can not upgrade my project to jdk 1.5 and 1.5 so i have to use jdk 1.5 only and similar case with ant also , now I have to onboard my project onto teamcity version 7 , but I have found that team city 7 minimum requirement is that you should have jdk 1.6 at least and ant version 1.8 at least which i do not have now please advise in such situation how can i set up or on board my project in teamcity.
TeamCity is itself written in Java, and so it requires JDK 1.6. However, that doesn't stop you also installing JDK1.5 as well as JDK1.6 on your TeamCity server and using Java 1.5 to build your project. (Our TeamCity server has JDK 1.6 and 1.7 installed on it and doesn't have a problem with that.)
I also can't see a problem with the Ant versions. TeamCity 7 ships with Ant 1.8.2, but that doesn't stop you using Ant 1.5. I haven't found a way to tell TeamCity to use an alternative version of Ant, but you can always use the command-line runner to run the correct version of Ant if you really need to.
After installing the BrightScript Eclipse Plugin for Roku development it acted like it installed fine but is not visible anywhere in Eclipse. What am I doing wrong?
I figured this out although I wasted a good part of two days trying to uninstall and reinstall the plugin on various eclipse versions. If you look here:
http://sdkdocs.roku.com/display/sdkdoc/Eclipse+Plugin+Guide
and look at the release notes for the 9/30/2013 release you'll see that it says the plugin is disabled if not running Java 1.7 or higher. I believe eclipse for mac ships with a version of Java but it must be older than this. I went here:
http://www.oracle.com/technetwork/java/javase/downloads/index.html
and downloaded the latest version and there it was. Hope this saves someone else some time.
The development of Eclipse support for Java 8 is ongoing in a branch (http://wiki.eclipse.org/JDT_Core/Java8).
To try out the current Eclipse support for Java 8, I did the following:
I installed a build of JDK 8 (This step is optional).
I checked out branch BETA_JAVA8 of git://git.eclipse.org/gitroot/jdt/eclipse.jdt.core.git.
I imported the checked out projects in an instance of Eclipse Juno SR1 (Build ID: 20120920-0800).
I ran a new instance of Eclipse from my running Eclipse.
To use the new syntax available in Java 8, Eclipse said that I have to set the compliance level of my code to 1.8. To set the compliance level, I have to set the execution environment to JavaSE-1.8. This execution environment was not available at Windows -> Preferences -> Java -> Installed JREs -> Execution Environments.
How can I set the execution environment to JavaSE-1.8?
The following summarizes some of my attempts to install the execution environment:
I followed the wiki instructions looking for a description of JavaSE-1.8 at the update site http://download.eclipse.org/eclipse/updates/4.2. But, the definition of the execution environment wasn't there.
I looked for the JavaSE-1.8 profile in the git repository of rt.equinox.framework, but, it wasn't there.
I just went to the Eclipse Marketplace from inside of Eclipse (Help/Eclipse Marketplace...) and installed the "Java 8 support for Eclipse Kepler SR2", and the new "JavaSE-1.8" execution environment showed up automatically. I had previously installed Java 8 and added it as a 'Installed JREs' entry. No need to mess with property files.
Think you just have to change the 'settings' directly in the 'preference file' : org.eclipse.jdt.core.prefs .
e.g. org.eclipse.jdt.core.compiler.compliance=1.8
If you have Kepler you can get it using a patch that has installation instructions on this page:
https://wiki.eclipse.org/JDT/Eclipse_Java_8_Support_For_Kepler
Starting with I20140318-0830 all Luna (4.4) builds on our downloads
page contain the Eclipse support for Java™ 8. For Kepler SR2 (4.3.2) a
feature patch needs to be installed. This page describes how to do
this.
Eclipse version >=Luna (that's one after Kepler) runs smoothly with java 8.
