java - Compiling any JavaFX project in NetBeans returns Unsupported major.minor version 52.0 -


i see number of similar questions

but none same circumstances mine. i've tried solutions anyway (when relevant) , haven't helped.

i had created javafx fxml application in netbeans 8.0.2 , had manually upgrade jdk 1.7 1.8 features wanted. believe using 1.8.0_52 both jre , jdk , project compiling fine. computer notified me of update 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

and java 8 fxml project gets above error message during compile-time, standard basic javafx fxml application comes netbeans. java 7 fxml compile 7 missing important features. i've started new projects specifying 8 , i've started new project in 7 , upgraded 8: same result.

i've ensured source/binary format jdk 8, in sources category , java platform set jdk 1.8 in libraries category of project's properties. can find no other setting update. i've tried clean build each time change setting. error happens in ide-generated file jfx-impl.xml large post in entirety, being on 4000 lines. post portion here. classpath="${javafx.ant.classpath}" line 406, compiler reports 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 = ${javafx.ant.classpath}" level="verbose"/>     <taskdef resource="com/sun/javafx/tools/ant/antlib.xml"         uri="javafx:com.sun.javafx.tools.ant"         classpath="${javafx.ant.classpath}"/>     <condition property="have-fx-ant-init">         <typefound name="javafx:com.sun.javafx.tools.ant:init-ant"/>     </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>

the error message is:

does have idea i'm missing? there bug in netbeans or in 1.8.0_60 sdk or jre? time & consideration!

you have change netbeans_jdkhome in netbeans.conf file.

  • close netbeans if running.
  • find file c:\program files\netbeans 7.3\etc\netbeans.conf
  • change value parameter "netbeans_jdkhome" desired jdk version
    e.g.: netbeans_jdkhome="c:\program files\java\jdk1.7.0_21"
  • save file , start netbeans again.
