I wish to compile my code with jdk 10 using eclipse IDE. For this I have added jdk-10.0.1 to installed jres and have selected that as my default
.
But in the compiler compliance level I do not get 10 in the dropdown. If only I could download java 9 which is currently not possible I could have compiled the same using java 9. Also eclipse photon which is the latest one available does not have java 10 in the dropdown
.
Question
How can I compile my code using java 10 with eclipse, since we need an upgrade from java 8 to java 10.
Java 9 support not available
Eclipse photon download link
Yes it worked with the latest version of oxygen eclipse. Thanks

*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.

Java 11 JaxB error
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".

Installing NetBeans 8.0.2 with JDK 9.0.1
(2 answers)
Closed 3 years ago.
NetBeans does not download and shows me the message shown in the image below, knowing that I installed the jdk 13 and included in the environment variables correctly
Based on the icon in the top left corner of your screenshot, it looks like you are trying to install NetBeans version 8.x using JDK 13. That is an invalid combination since NetBeans 8.x only supports the use of Java 7 or Java 8.
From the NetBeans IDE 8.0.2 Installation Instructions:
The Java SE Development Kit (JDK) 7 Update 10 (or later) or JDK 8 is
required to install NetBeans IDE.
So unfortunately that error message is more than misleading; it is incorrect. Using releases newer than JDK 8 simply won't work.
To fix the problem you should install the latest release of JDK 8 before repeating your installation of NetBeans.
Alternatively, you could download and install the latest version of NetBeans, Apache NetBeans 11.1. That approach is definitely preferable if it is feasible for you it since it offers three advantages:
You are using the latest version of NetBeans.
You are using the most recent JDK.
Since you have already installed JDK 13 you won't need to download any other JDK. Apache NetBeans 11.1 will run fine using JDK 13.
Does VS Code (code-runner extension) support JDK 1.8? In the morning I was using JDK 12 , but then I downgraded to JDK 1.8 to try out applet viewer and stuff. Unfortunately now it doesn't even highlight the code.
Someone please tell me the problem and its solution.
JDK 1.8 is supported by VSCode.
Read https://code.visualstudio.com/docs/languages/java and install needed extensions.
Update 2021
Currently to use the Java extension in VSCode its required JDK 11, but you can still use older versions of JDK in your projects. See this to get information about how to configure other JDK version for your project.
Java 1.8 was no longer supported since "Language support for Java" extension upgrade to 0.68.0, I downgraded to 0.64.1 which works for me.
As stated here:
Note: Although the Java language server requires JDK version 11 or above to run, this is NOT a requirement to your project's runtime.
This means that you need to have JDK 11 or higher installed. You can also install older JDKs and configure the runtimes. Just open the Command Palette (Ctrl+Shift+P) and type the command Java: Configure Java Runtime. If you have JDK 8 installed and have properly configured maven or gradle, this isn't even necessary. Visual Studio Code will correctly pick up the correct JDK.
VS Code no longer supports JDK 1.8. The "Java Extension Pack" relies upon "Language Support for Java(TM) by Red Hat" which documents Java 11 is the minimum requirement. See here: https://marketplace.visualstudio.com/items?itemName=redhat.java
Tis unfortunate, guess I'm switching back to eclipse
I have been using Netbeans upto 8.2 for several years. But now I have installed JDK 10 and was forced to migrate to Eclipse. But I do not feel very comfortable. I would like to go back to Netbeans.
Does Netbeans support JDK version 10 now? I mean July, 2018.
Yes, NetBeans supports Java 10, but there are several important caveats to be aware of:
NetBeans 8.2 does not support Java 10. It just won't work.
NetBeans 9 supports Java 10. It was released yesterday (July 29, 2018).
NetBeans 9 only officially supports Java SE. Some options (plugins) available on NetBeans 8.2 are not provided on NetBeans 9 by default, such as Java EE and C/C++. However, there is a way to add those options (at your own risk). See this answer to How to get Netbeans 9 to deploy a valid webapp on Tomcat for details. Also see What's Happened to My Favorite NetBeans Plugins?
Notes:
NetBeans 8.2 is an Oracle product, but they are in the process of handing the NetBeans components over to Apache, and NetBeans 9 comes from Apache. The transition explains why many plugins are not available in the initial release of NetBeans 9, but they will become available in coming releases.
The NetBeans 9 download is in the form of a single zip file for all operating systems. Just unzip to a folder, then locate and run netbeans64.exe (or netbeans.exe for 32-bit).
Updated to add further notes:
You can safely install and run NetBeans 8.2 and NetBeans 9 concurrently.
The default platform for NetBeans 9 is still Java 8. You must explicitly add JDK 10 as a platform: Tools > Java Platforms > Add Platform...
To create a Java 10 project, open the project's properties and ensure that the following are set:
Properties > Libraries > Java Platform: JDK 10
Properties > Sources > Source/Binary Format: JDK 10
An easy way to verify that JDK 10 is set up correctly is to create a trivial Java application and put this code in the main() method: var v = 123; System.out.println("v=" + v); If that compiles and runs you are fine (and vice versa).
Netbeans 9 started working for me after I moved to JDK 10.0.2 instead of 10.0.1 ..... may be it will help guys who are struggling like me.
Enjoy.
I've an old machine running Windows XP 32.
Because Oracle dropped support for WXP 32 bits, I've manually installed the jdk following
the awesome answer here:
installing JDK8 on Windows XP - advapi32.dll error
I've however not added it yet to the JAVA_PATH, which is set to jdk 6. I don't know if it would harm or not to add it as well, but I want to be conservative here because a lot of programs in this machine need jdk 6. I don't want to break anything working now.
I'd like to toy around in eclipse to test the new Java 8 features. I've manually added the new jre 8 in the "Installed JREs" section under window -> preferences. In the compiler combo, the highest level available is 1.7 (installed jdk7 some time ago, this time using the official installer, but I still keep java 6 as the default in the system). I don't see any option to add the new level.
Consequently, when creating a new project using the new JRE, a warning is shown saying:
The current workspace uses a 1.4 JRE with compiler compliance level
1.6. This is not recommended and either the JRE or the compiler compliance level should be changed.
Seems a problem derived from the manual installation of the JDK.
I'm using Eclipse Kepler v4.3.1, but I have also tested this in older 3.x install with identical results.
Any help will be appreciated.
Support for Java 8 in Eclipse Kepler 4.3.2 is described here. This basically says specify
http://download.eclipse.org/eclipse/updates/4.3-P-builds/
as the 'Work with' site on Install New Software and select 'Eclipse Java 8 Support'.
Recent builds of Eclipse 4.4 Luna (since 18 March 2014) have Java 8 support included (but Luna is still under development).
Update:
Eclipse Luna (4.4) was released on 25 June 2014
