![]() ![]() īuilds, tests, and runs the project Project1Part1. if you are not sure about the version of jdk, you can find it by typing in CMD java -version. I removed commented sections for readability. go to C:Program FilesNetBeans 8.0.2etc, open the file nf then change netbeansjdkhome to the path of your JDK, netbeansjdkhome'C:Program FilesJavajdk'. Once the Clean and Build or even the Build option is chosen in NetBeans, I haven't found a way to force recompilation for execution within the IDE other than making a trivial change to allow a resave of some file in the project.Īdding my project's build.xml by request. My problem was that I'm used to Clean and Build meaning something different, so I was running a Clean and Build every time I wanted to run the application in the IDE. Likewise, if the user selects Run, all unsaved files will automatically be saved and compiled before NetBeans runs the application. When a file is saved, NetBeans automatically compiles the project by default, as per: I was using only the Build and Clean and Build options, which are not for compiling an application to run within the IDE. I upgraded my version of Ant from 1.9.4 to 1.9.6 as a shot in the dark based on other postings I saw, it made no difference. JButton cardPickerButton = new JButton("Card Picker") ĬtPreferredSize(buttonSize) LayoutManager layoutMgr = new FlowLayout() ĭimension buttonSize = new Dimension(150, 20) JFrame frame = new JFrame("Project 1, Part 1") įtDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) However, it will be reflected if run from command line. If I change the ctor string arg, the change will not be reflected when I clean, build, and run in NetBeans, (or if I just build and run without clean). As an example of my problem, note the button initialization in File 2. I get around it by building from CLI but that's getting old really fast, it would be nice to be able to run from w/in the IDE.įollowing is some context code. also try running netbeans from command line, so you may see any errors on the console. if it still doesnt work, update your post with JDK as well. But an older version of the application will run with no changes reflected. try removing netbeans completely, reboot your computer and then install it again. (or install JDK 8 and then do the same process) Share. Just change the directory for JDK from 9 to previous version if it is installed. No errors, I just get a BUILD SUCCESSFUL notification in Output. For that you would have to go to: NetBeans 8.2etc. by pressing Shift+F11), then run from in NetBeans (e.g. If I make a code change in NetBeans, and Clean and Build (e.g. 2 Answers Sorted by: 4 +50 This error is reported as a bug in NetBeans (with a resolved status as it turns out to be considered as a 'user error'). If I update the code and repeat the process from CLI, the new changes are reflected as expected. ![]() MySQL Connector/J 8.0 and higher is compatible with all MySQL versions starting with MySQL 5.7. Compiling from command line with javac is successful and the program runs as expected. Java Programming NetBeans IDE You can download a zip archive of the finished project. MySQL Connector/J is the official JDBC driver for MySQL. I wrote my code in NetBeans and saved it. I'm using NetBeans to build and run a Java Swing project for school.
