Product Version = NetBeans IDE 7.4 RC1 (Build 201309162201) Operating System = Mac OS X version 10.8.5 running on x86_64 Java; VM; Vendor = 1.7.0 Runtime = Java HotSpot(TM) 64-Bit Server VM 23.25-b01 Although Java 8 is selected, if NetBeans runs on JDK 1.7, you will get the following error attempting compiling Java 8 / javafx applications: ------------------------------------------------------------- COMPILATION ERROR : ------------------------------------------------------------- Failure executing javac, but could not parse the error: javac: invalid target release: 1.8 Usage: javac <options> <source files> use -help for a list of possible options Also NetBeans reports errors in the editor and cannot find JavaFX classes. Reproducer: try to build the project https://github.com/AdamBien/lightfish/tree/master/multilight/lightview with NetBeans on OSX running on JDK 1.7.

What do you mean by "Although Java 8 is selected..." ? Go to Project | Properties | Compile ... what is selected in "Java Platform" field ?

Java 8 of course :-). I think the issue is the path. NetBeans probably uses the JDK visible in JAVA_HOME for maven compilation and does not change that with this setting mentioned above. My JAVA_HOME points to JDK 1.7. Before I start maven from command line (without NB) I point to JDK 1.8 and it works then.

The current algorith is following. 1. when a java platform is selected in the project UI, it's used. 2. if not and JAVA_HOME is defined, then it's used. 3. as a fallback default platform used to run the IDE is used. oh actually there's 0. if Env.JAVA_HOME= property is used in the action execution props, it's used. It has highest priority to be able to override jdk usage for single action execution. effectively a non-project based execution (typically just new project creation) will skip step 1. and only rely on 2+3. That way it can use different jdk tha project based executions.
BTW does the initial line of the output in the IDE mention the JAVA_HOME env var? does it point to a valid 1.8 jdk folder? one thing that could be wrong is this code: getJavaPlatform().findTool("java") - the java platform manager doesn't find the java tool or.. getJavaPlatform().getInstallFolders() - it's install folders don't contain the returned fileobject for java tool. It could be that our code is wrongly handling jdk on mac and fails in one of these methods. Then you should be seeing jdk 1.7 in the build output's header. As that's the default we fall back.
I can confirm the bug is real, Adam showed it to me yesterday. I tried to make it go away (bundled vs. unbundled maven, clean userdir), but no luck.

I'm having bit of a problem with the jdk installations. 1. installing 1.8 sort of make it the default no matter what (I've installed 1.7_40 afterwards but still 1.8 is the default jdk even though just early access) 2. googling around I found http://docs.oracle.com/javase/7/docs/webnotes/install/mac/mac-jdk.html but even though setting JAVA_HOME env var to 1.7 works for the cmd line (eg java -version), netbeans seems to keep on picking up jdk 1.8. 3. So I've edited the netbeans.conf file and that finally makes netbeans pick up 1.7. Then when I set jdk8 as java platform for a project and run a build, the output correctly points to jdk8 JAVA_HOME. in what way is your setup different? I'm on osx 10.8.5
I'm setting the JAVA_HOME in ~/.profile. (.zprofile in my case) I actually have to. I have to use Java 7 for my daily work. I'm using Java 8 currently for evaluation only,..

I'm using Java 8 > currently for evaluation only,.. and netbeans picks it up? I've added JAVA_HOME to my .profile, restarted but netbeans continued to use jdk8. That's the reason I've already once just deleted jdk8 after quick evaluation.
I've workarounded my netbeans startup problem with installing 1.8 only after running netbeans. and I cannot really reproduce your problem on my computer. 1. netbeans running on 1.7_40 2. just building the project fails as the jdk used is the IDE's jdk (1.7_40), That's correct 3. I've created a Java paltform for 1.8 and set it in the project's Compile panel. (new file nbconfiguration.xml is created with <netbeans.hint.jdkPlatform>JDK_1.8</netbeans.hint.jdkPlatform> property). Then the build is started with jdk 1.8 correctly. I was not able to find this property in the codebase. (no netbeans.hint in effective pom) neither was this nb-configurations.xml file around before. So I'm not sure how you setup the jdk 8 for use in the project. The way it should be is to either set the jdk1.8 in all project's customizers or put the netbeans.hint.jdkPlatform property in the parent pom. When someone without the jdk1.8 platform opens your projects, we ill notify him/her that it's necessary to define a java platform with given name. PS: I had JAVA_HOME set to 1.7_40
I have this problem with netbeans 8
