After I upgraded Netbeans from 12.6 to 13, Netbeans doesn't start. When I start it from the command line, I got the following message:
java.lang.IllegalStateException: Missing hosting module org.netbeans.libs.javacimpl for fragment org.netbeans.modules.nbjavac.impl

What's the reason? How can I fix it?
This is caused by old nb-javac (Netbeans Java Compiler) modules installed in an older Netbeans version, which are incompatible with nb-javac, which is now bundled in Netbeans.
It's necessary to remove those old modules. You can find them in the Netbeans user directory. On Linux this is for example in ~/.netbeans or in ~/snap/netbeans/current, if installed as a Snap package. Those nb-javac files are in the modules directory in that directory (e.g. ~/.netbeans/modules) and include nbjavac in the name, e.g. org-netbeans-modules-nbjavac-api.jar. Delete all such files that include nbjavac. Then start Netbeans again, all should work now.
This problem was reported for a development version of Netbeans 13 on the developers' mailing list: https://www.mail-archive.com/dev#netbeans.apache.org/msg09777.html. There are original instructions that helped me to fix this issue. I wasn't using any development build of Netbeans, I just upgraded from the regular version 12.6 to the version 13 of Netbeans. In Netbeans 12.6, I installed the nb-javac plugin, which probably brought these incompatible modules that needed to be removed.

I reinstalled my android studio since the sdk was not found and so on. After re installing java jdk and android studio , everything worked well until I got an error saying 'Could not initialize class org.codehaus.groovy.runtime.InvokerHelper' which I solved by changing the Gradle version. And now the error is 'Type 'FlutterTask' property 'assets' is missing an input or output annotation.'
FAILURE: Build failed with an exception.
What went wrong:

I also had this problem So I did install java 8
You might have Java 13 So install Java 8
Java JDK 16 is the one that seems to lead to this issue try downgrading by downloading a lower version of JDK preferable JDK 8 or 11
To future individuals who will run to this error. Here is the link to download the JDK enjoy your coding experience don't forget to change the path too.
https://www.oracle.com/java/technologies/javase-downloads.html
mainly you have jdk16 i tried to install java 8 and set env to java 8 it worked for me
Try installing the latest Gradle package gradle-7.1.1, if you are using Java JDK 16 installed. To do this open android/gradle/wrapper/gradle-wrapper.properties file and under distribution url, update the gradle version to 7.1.1 (or the latest). After that, inside your Flutter project directory, run the following command in the terminal:
cd android && ./gradlew
I removed the JAVA_HOME path to the JAVA download and changed JAVA_HOME path to the following:
C:\Program Files\Android\Android Studio\jre
I am now coding
FOUND IT !
No need to change your JDK version, follow the steps to resolve the issue:
check your java version and remember it, use "java -version" in terminal
go to your android studio path installation
then in: Android Studio/jre/ open the file named "release"
take attention of the value of JAVA_VERSION field
if it's not the same as the java version on your computer, just change it with the version installed on your computer.
That's it, i hope it will resolve your issue like it resolves mine.
Try it and give a feedback.
Try this!
Remove package android from the top of settings.gradle. This helped me out.
If this error occurs, this might because you have installed the latest JDK such as JDK 16. You download and install JDK 8 and uninstall JDK 16. Then restart the desktop/laptop and try launch and run flutter run again. It should be working fine.
In my case, on Windows 10, my JAVA_HOME was set to JAVA SE 16 C:\Program Files\Java\jdk-16 and when I looked at the release file in java jre in android studio, C:\Program Files\Android\Android Studio\jre\release, I found that the the JAVA_VERSION WAS "11.0.10" (java 11) for short. So I changed the java installation on my PC to Java 11, update JAVA_HOME in my environment variables to point to the new java (C:\Program Files\Java\jdk-11.0.12) and restarted android studio, Then everything worked.
You can get your java 11 from here.
https://www.oracle.com/java/technologies/javase-jdk11-downloads.html. Change 11 to 8, 16 etc to get the download link for the java version you need.
The problem has to do with having Java 13 or 16 installed on your computer. The current version of Flutter does not work with Java 13 and 16. Just uninstall either of these that you may have installed and installed Java 8 or Java 11. Restart your computer to effect the update. Everything should be fine afterwards
I got this error when using flutter. I fixed it ensuring the android-studio-dir path was set correctly.
You set it up using flutter config --android-studio-dir="android studio path".
Then run flutter doctor and ensure flutter can see Android Studio
In 'adnroid/gradle/wrapper/gradle-wrapper.properties'
Change distributionUrl to version 7.0.1
In 'android/build.gradle'
Change 'com.android.tools.build:gradle' to version 4.2.0
Java 11 is the only supported version by Flutter as for now. It compiles and installs.
Previously I had this error using Java 19 and Java 8.
You might want update your gradle version.
Check the supported gradle <-> kotlin <-> java version on their page.
You can try this, it works for me.
Open the android module to a new window and automatically download all necessary libraries after successfully building finished run the app.
Simply go to your Android Studio path -> C:\Program Files\Android\Android Studio
open jbr folder -> copy all files -> then go back -> paste all the files in the jre folder and "replace the files in the destination".
It works for me in two different laptops. I have latest jdk version - 19.0.2
The error message you're seeing is related to the flutter build process and it occurs when a required input or output annotation is missing from the assets property of the FlutterTask.
task buildFlutter(type: FlutterTask) {
// Add the #Input annotation to the assets property
#Input List<String> assets = ["assets/images/", "assets/fonts/"]
}
Try to disable AVAST, check system vatiables path for JDK and SDK, clear cache with yarn.
I have an issue and after many attempts don't know how to resolve it.
I have Java/Maven project with JDK 6 and installed Maven 3.2.5 in Eclipse Luna
Now I'm trying to run clean install command to create ZIP package but getting the following error message:
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project ABC: Fatal error compiling: invalid target release: 1.7
Does someone has this issue before and how do you resolve it.?
Could you help me please?
Thanks in advance.
The project you are attempting to compile specifies that the generated bytecode should be for Java 1.7. To do that you have to have a JDK7 or later.
Either change the project to specify 1.6, or upgrade your Java to 1.7. (There is really no reason to still stay on Java 1.6, it is old and obsolete now.)
I am having a strange issue. I am using maven 3.2, java 1.6 and jboss 5.1.
I am using all these old version because I have some system requirement.
I am working on web application.
I am getting an error
Fatal error compiling: tools.jar not found: C:\Program Files\Java\jre6\..\lib\tools.jar ->
imperviously it was working fine. When I made some changes in code and when I did this from that time I am getting This error.
I tried updating maven forcefully.
I tried maven install from eclipse.
Even I downloaded the missing jar and put into C:\Program
Files\Java\jre6\..\lib\ this path.
and many more still I am getting this error. please help me.
I think your eclipse is pointed to JRE not JDK. Can you point it to JDK and check?
Mistake you did is ---
Your build path is pointing to the wrong JRE directory/folder. So, you have to change the build path to JRE folder(which is inside the JDK folder) rather not the JRE folder that's available outside the JDK.
Eclipse > Select Windows > properties > Java > Installed JREs
• Select the "jreX" under the Installed JREs list > Select "Edit" or double click
• Your JRE home directory location may be pointing to something like
JRE home: C:..\Java\jre1.x --- (which is wrong)
• Point to the right directory as follows:
JRE home: C:..\java\jdk1.x\jre --- (this is right)
• Finish.
Clean your project and compile it. It should work fine :)
I am running Eclipse 4.2, PyDev worked fine with it until recently it stopped working (there is no longer a PyDev View), if I try to update pydev, I get this error:
Cannot complete the install because one or more required items could not be found.

I just realised it says: org.eclipse.rcp.configuration_root.gtk.linux.x86. I recently upgraded my system from 32bit to 64bit, might that be the reason and if it is the reason how can I fix it?
Removing ~/.eclipse and reinstalling all plugins solved the problem.
