How to Disable CSS Warning "Unknown Property" in Eclipse Mars

How to disable css warning Unknown property in Eclipse Mars?

I filed an e(fx)clipse bug [1] and uninstalled e(fx)clipse for the time being.

The main reason why I had installed e(fx)clipse at the beginning was to get rid of the access restriction warnings related to jfxrt.jar (also see [2]). Now I use additonal access rules for the JRE container in my classpath file instead of using e(fx)eclipse:

<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
        </attributes>       
        <accessrules>
            <accessrule kind="accessible" pattern="javafx/**"/>
            <accessrule kind="accessible" pattern="com/sun/javafx/**"/>         
        </accessrules>  
</classpathentry>

[2] Using JavaFX in JRE 8

Eclipse doesn't see JavaFX properties in css file, unknown property

Solution:
Delete e(fx)clipse plugin; try to install again from

http://download.eclipse.org/efxclipse/updates-released/3.6.0/site

https://download.eclipse.org/efxclipse/updates-nightly/site

, probably you will be noticed that due unsatisfied dependencies version will be automatically downgraded (3.6.0 -> 3.5.7 in my case). If so, install m2e support from same repository:

servlet on eclipse asks me do you want to save this file or find a program online to open it when run on server

You misspelled your content type.

Since the browser doesn't know how to display test/html, it offers to save it instead.

Using JavaFX in JRE 8, “Access restriction” error

From the Eclipse Point of view the error is totally correct because JavaFX is coming from the extension classpath and is not available on ALL Java8 VMs (e.g. ibm!).

As outlined you can suppress those warnings by add access-rules or IMHO the best solution is to install e(fx)clipse which does this automatically for you and beside that even provides you tooling for JavaFX CSS and FXML.

You can grab an all in one package from http://efxclipse.bestsolution.at/install.html
