While debugging java application in eclipse, the dialog for opting Relaunch/terminate appeared. I have selected the option to terminate the application, but now unable to change this option.
In eclipse settings, section Java > Debug, try checking the box 'Show error when hot code replace fails'.

I'm trying to migrate from Eclipse to Android Studio. There are a few things that bug me, but one stands out:
Q1: Is there no way to do automatic builds and have a list of problems displayed immediately like in Eclipse?
I know, there are many refactoring tools, but my often-used practise is to just insert a character into the name of a method and variable and check problems-view to see where it's being used.
Q2: How can replace or replicate this workflow in Android Studio?
One thing you can do is deactivate the external build. To do so click on "compiler settings icon" in the "Messages Make" panel that appears when you have an error. You can also open the compiler settings by going to File -> Settings -> Compiler. (Thanx to #maxgalbu for this tip).
enter image description here
Uncheck "Use External build"
enter image description here
And you will see the errors in the console
EDIT: After returning to "internal build" again you may get some errors, you can solve them this way: Android Studio: disabling "External build" to display error output create duplicate class errors
I need to connect to Matlab from Java using matlabcontrol.
I tried their demos and those are working fine but when I tried to connect to Matlab using my application in Java RCP e4 I get this error (to be clear, my code succeeds in opening an instance of Matlab but afterwards the following appears in the Matlab window):
??? Undefined variable "matlabcontrol" or class "matlabcontrol.MatlabClassLoaderHelper.configureClassLoading".
And this appears in the eclipse server window:
matlabcontrol.MatlabConnectionException: MATLAB proxy could not be created in 180000 milliseconds
I tried searching for the answer and this came up: http://code.google.com/p/matlabcontrol/wiki/Compatibility
They say here that if this error comes, to run this command in Matab: java.lang.System.getProperty('java.class.version')
And if the answer is 50 or greater then matlabcontrol should work, but it doesn't for me.
I can't understand what's wrong (demo works, my code doesn't) and I'm desperately in need of an answer. This is for a project due soon and I would appreciate all the help I can get.
I faced a similar problem. This is what I did to solve the problem.
Go to the properties of your project in Eclipse. You can do this by selecting your project in "Package Explorer" and pressing Alt+Enter or by simply selecting properties on right click context menu.
In properties window, select "Java Compiler" and uncheck "Use compliance from execution.... 'JavaSE-1.8' on....". After that select "1.7" from drop down menu in "Compiler compliance level"
I hope this solves the problem for you!
I have a Java Maven Project started in Eclipse, worked on it a few days, then imported it in IntelliJ IDEA, again working on it a few days.
The normal Run/Execution in IDEA and via shell does work, but not the Debug.
When I click the Bug Icon for Debug, it opens up URLClassLoader.java file and points on the Line "throw new ClassNotFoundException(name)" and pauses the Debug, if I click Resume Debug, it shows several Classes that do not belong to my project. I can click the Resume Button endless, it shows the same classes, also ClassNotFoundException over and over again in a continuously loop and does not debug my source.
If I click Build -> Rebuild Project it says at the Debug icon
"Hot Swap failed
myClassname: schema change not implemented;
myClassname: Operation not supported by VM"
In the Debug window under Variables it says: "Frame is not available"
The Debug of this project in IntelliJ IDEA did work previously, whats wrong now?
Looks like you have an exception breakpoint on ClassNotFoundException. Please try to open Run | View Breakpoints... and uncheck the breakpoint under "Java Exception Breakpoints".
in my situation, just neglect the evaluate language drop down.
This is really helpful. Go to your breakpoints in debug mode and make sure to deselect all the breakpoints first and then select only the ones in your class.
I'm using a plug-in in Eclipse. This plug-in provides a feature to the Eclipse menu (when I right-click). I would like to capture the value that a user selects. Is there anyway in Java to do that since this added feature is not added by my project but by the plug-in ?
you can use the debugger feature in eclispe.. set toggle points and run the application in debugger mode.. this way you can trace the values coming in after each statement is executed..
Check this image
Eclipse debugger http://s19.postimage.org/6x3yy8a43/eclipseimage.png
The blue dot refers the toggle breakpoint.. use the mouse left click to place it on the statement u like... and run the project in debugger mode see top of the image..
press F6 to execute next statement in the debugger mode
Hope this helps
Cheers
How do I disable "Scan for external changes" in netbeans ?
By Unmarking the checkbox here
Go to menu: Tools/Options/Miscellaneous/Files => ❑ Enable auto-scanning of sources
In Netbeans(Windows), Go to "Tools > Options > Miscellaneous/Files ", You will
find an option called "Enable auto-scanning of sources".
In case if you want to manually refresh (scan) your sources. Then right click the folder in Netbeans Projects window (or any explorere window like Favourites, Files, etc.,) you will find the option called 'Refresh Folder'.
Note : This option will be enabled only after you disabled the auto-scanning options.
On Mac go to menu:
NetBeans/Preferences/Miscellaneous/Files and uncheck ❑ Enable auto-scanning of sources
Works for NetBeans version 8.0.2, MacOs 10.10.2 Yosemite
I'm using MAC Netbeans 8.1 and I dont have NetBeans/Preferences/Miscellaneous/Files Can someone help please? checking external changes is using all CPU
I dont have Preferences in my main menu
PS: I found my solution; I just mention it for others who run into the same issue ; just use this short key to open Cmd-, to open the menu: NetBeans/Preferences/Miscellaneous/Files
