Is there any way where I can increase the Java Compiler Compliance level of Eclipse 3.5 to 1.7. (i.e.) By adding a plugin/add-on. Since by default this will not support the JDK 1.7 compliance.
We have a constraint in Eclipse upgrade, since it's an RCP application.
Any thoughts on this will be greatly appreciated.
Thank You.
Old eclipse version doesn't support java 7. You will have to download at least eclipse-3.8M1 version.
To conclude, there is no way to enable Java 7 Compliance in Eclipse 3.5. Have to migrate to 3.7 at least. Thanks a lot for your responses.
Windows --> Preferences --> Java --> Installed JRE --> Add --> Standard VM --> Then Select the JDK 7 and set it as default.
PLease check the image to change the setting make it your default under the Compiler setting.
