编译在NetBeans的JavaFX项目返回不支持的版本MAJOR.MINOR 52.0 [英] Compiling any JavaFX project in NetBeans returns Unsupported major.minor version 52.0
问题描述
我看到一些类似的问题。
I see a number of similar questions
- Netbeans 8.0不支持的版本MAJOR.MINOR 52.0错误
- Unsupported MAJOR.MINOR版本52.0错误（一式两份）
- Running一个JAR我编译：不支持MAJOR.MINOR版本52.0
- Can't即使固定配伍后修复不支持的版本MAJOR.MINOR 52.0
- Netbeans 8.0 Unsupported major.minor version 52.0 error
- Unsupported major.minor version 52.0 Error (duplicate)
- Running a JAR I compiled: Unsupported major.minor version 52.0
- Can't fix Unsupported major.minor version 52.0 even after fixing compatibility
但没有使用相同的情况下为我的。我反正（相关时），尝试他们的解决方案，他们并没有帮助。
But none with the same circumstances as mine. I've tried their solutions anyway (when relevant) and they haven't helped.
我在NetBeans 8.0.2创建一个JavaFX应用FXML并有JDK手动升级1.7到1.8来获得的功能，我想。我相信我是用1.8.0_52的JRE和JDK和项目编制精细两者。然后我的电脑我的通知更新的用于Java 8.现在：
I had created a JavaFX FXML Application in NetBeans 8.0.2 and had to manually upgrade the JDK from 1.7 to 1.8 to get features I wanted. I believe I was using 1.8.0_52 for both the JRE and the JDK and the project was compiling fine. Then my computer notified me of an update for Java 8. Now:
mc@MC-Desktop:~$ java -version
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)
mc@MC-Desktop:~$ javac -version
javac 1.8.0_60
和突然任何Java 8 FXML项目在编译时得到上面的错误消息，甚至连基本的标准的JavaFX应用FXML 附带的NetBeans。 Java 7中FXML将编译，但7缺少重要的功能。我已经开始指定8个新项目，我在7开始了一个新的项目，然后升级它8：同样的结果。
and suddenly any Java 8 FXML project gets the above error message during compile-time, even the standard basic JavaFX FXML Application that comes with NetBeans. Java 7 FXML will compile but 7 is missing important features. I've started new projects specifying 8 and I've started a new project in 7 and then upgraded it to 8: same result.
我已经保证了源代码/二进制格式为JDK 8，在资源类和Java平台在项目属性的库类别设置为JDK 1.8。我找不到任何其他的设置进行更新。我每次我更改设置的时间尝试了干净的构建。在IDE中生成的文件 JFX-impl.xml中的过大后的全部，是超过4000行发生错误。我在这里发表的部分。在的classpath =$ {} javafx.ant.classpath为406线，在编译器报告错误：
I've ensured that the Source/Binary Format is JDK 8, in the Sources category and the Java Platform is set to JDK 1.8 in the Libraries category of the project's properties. I can find no other setting to update. I've tried a clean build each time I change a setting. The error happens in an IDE-generated file jfx-impl.xml that is too large to post in its entirety, being over 4000 lines. I post a portion here. The classpath="${javafx.ant.classpath}" is line 406, where the compiler reports the error:
<target name="-check-ant-javafx-version" depends="-pre-check-ant-javafx-version,
-set-endorsed-javafx-ant-classpath,-set-javafx-ant-classpath" if="do.check.ant-javafx.version">
<echo message="ant-javafx.jar.location = ${ant-javafx.jar.location}" level="verbose"/>
<echo message="javafx.ant.classpath = ${javafx.ant.classpath}" level="verbose"/>
<taskdef resource="com/sun/javafx/tools/ant/antlib.xml"

</condition>
<property name="ant-javafx-version-already-checked-in-jfximpl" value="true"/>
<echo message="have-fx-ant-init = ${have-fx-ant-init}" level="verbose"/>
</target>
错误消息是：

有没有人有一个想法，我缺少的是什么？有没有在NetBeans或1.8.0_60 SDK或JRE中的错误？感谢您的时间和放大器;考虑！
Does anyone have an idea what I'm missing? Is there a bug in NetBeans or in the 1.8.0_60 SDK or JRE? Thanks for your time & consideration!
推荐答案
您必须改变netbeans_jdkhome在netbeans.conf文件。
You have to change netbeans_jdkhome in netbeans.conf file.
- 关闭的NetBeans如果它正在运行。
- 找到文件C：\\ Program Files文件\\的NetBeans 7.3 \\等\\的netbeans.conf
- 更改值参数netbeans_jdkhome到所需的JDK版本结果
例如：netbeans_jdkhome =C：\\ Program Files文件\\的Java \\ jdk1.7.0_21 - 保存文件并重新启动NetBeans。
