I resolved the problem by removing and readding the JDK to the build path. Don't ask me why this works, though.

blocks|key|4639664|text|从Eclipse的角度来看，这个错误是完全正确的，因为JavaFX来自扩展类路径，并不是在所有Java8+VM(例如ibm!)上都可用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4639665|如上所述，你可以通过添加访问规则或IMHO来抑制这些警告，最好的解决方案是安装e(fx)clipse，它会自动为你做这件事，除此之外，它甚至还为你提供了JavaFX、CSS和FXML的工具。|4639666|您可以从http://efxclipse.bestsolution.at/install.html获取all+in+one包|offset|length|4639667|entityMap|0|LINK|mutability|MUTABLE|url|http://efxclipse.bestsolution.at/install.html^0|0|0|4|19|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@$F|S|G|T|1|U]]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

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 <a href="http://efxclipse.bestsolution.at/install.html" rel="noreferrer">http://efxclipse.bestsolution.at/install.html</a>

As James_D already suggested I added access rules to my classpath file. I uninstalled the e(fx)clipse plugin for the time being because it has a css validation bug (see <a href="https://stackoverflow.com/questions/31817620/how-to-disable-css-warning-unknown-property-in-eclipse-mars">How to disable css warning &quot;Unknown property&quot; in Eclipse Mars?</a>).

Here is my entry in the classpath file for the JRE container: 

<pre><code>&lt;classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.‌​launcher.StandardVMType/JavaSE-1.8"&gt;

I had the same problem. I used James_D 's solution but his exact solution did not work for me. But using <code>**/javafx/**</code> instead of <code>javafx/**</code> solved the problem for me. Hope that helps.

PS: I would post this as a comment under James_D 's solution but I just registered and did not have enough "reputation" to do so.

When trying to use javafx related classes in my new java 8 project I get an access restriction error from eclipse. So far the only 'solution' I've been able to find is to tell eclipse to ignore the access restriction, but I am not satisfied with that.
An example of the error: 

<pre><code>Access restriction: The type Pane is not accessible due to 
restriction on required library C:\Program Files\Java\jre8_0\lib\ext\jfxrt.jar
</code></pre>

I'm using Eclipse Kepler with the Eclipse JDT patch for java 8.

This seems to be an issue related to the fact that JavaFX is not a part of the JavaSE execution environment.

I am now toughly confused as according to <a href="http://en.wikipedia.org/wiki/JavaFX">http://en.wikipedia.org/wiki/JavaFX</a> javaFX is a part of the JavaSE. Is it possible that Eclipse is not recognizing that it is a part of the javaSE?

当我尝试在新的java8项目中使用javafx相关的类时，我从eclipse得到一个访问限制错误。到目前为止，我能找到的唯一“解决方案”就是告诉eclipse忽略访问限制，但我对此并不满意。错误的一个示例：Access restriction: The type Pane is not accessible due t...
