These problems just came out of the blue as for yesterday everything was working fine, today I was trying to debug my flutter app when this error showed up
I even made a new flutter project just to be sure it has nothing to do with my code, and tried to run the flutter starters app, but I still got the same error.
Not only that I noticed strange behavior when I opened the task manager.
I have absolutely no idea what went wrong and what's not working, I tried to restart my pc several times with no success. This happened to me before! But I thought it was due to slow internet connection at the time my internet was barely useable, when my internet connection got better it worked again, however this is not the case this time my connection is stable and fast so I have no clue where this is coming from. Trying to build it multiple times every time I get a different error.
Like this:
And this:
If someone could tell me what's going on and how to fix this, since I'm completely clueless.
Any info would be much appreciated.
gradle --stop suppose to stop all daemons .
2nd you can try to add _JAVA_OPTIONS : -Xmx1024M to your gradle.properties
and lastly you can try to manually stop them manually and try again . this look bad but it should work .

I'm trying to learn Spring. I followed a tutorial with Java and Maven, and everything worked perfectly, However, I wanted to use Kotlin instead of Java, so I generated a new project by following this tutorial.
The first time I launched the app, I had no problems, but when I relaunched it, I received this exception:
Error: Could not find or load main class com.example.blog.BlogApplication
Caused by: java.lang.ClassNotFoundException: com.example.blog.BlogApplication
This error occurs with Java and Kotlin, and my class exists and is correctly compiled, so the only one problem comes from Gradle.
I found 2 solutions to fix this error:
Removing directory ".gradle/6.8.3"
Using an older version of gradle (5.6.4 instead of 6.8.3)
Of course, these are not fully satisfying and I'd like to use the latest version.
Does anyone have an idea? Is it simply impossible?
Ok. This is just not possible as said in this issue : https://github.com/spring-projects/spring-boot/issues/24225

This is a problem I'd like to share with everyone. Also - I have resolved it and it was a pretty interesting problem.
When I received my laptop from repair I had my OS reinstalled. Everything (I mean whole configuration and programming environment) I had to do once more time from scratch.
It took some time, but the next day I was able to return to my work.
Problems started when I tried to run my Java - Spring App. I could run it, but immediately I was facing an error. Within the console, I have read that it was called a broken pipe error.
The solution for this error was to rename the account name in the registry. My account name was using special characters (f.e. like Ü).
I have created a second user with the role of admin. Later I have used win + r, typed regedit, and fired it.
When the Registry Editor has opened, I've entered HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList and in there I've found an account of mine. After that, I have changed ProfileImagePath for the desired name.
In the end, I have changed the name of the folder %SystemDrive%\Documents and Settings<Your_Name_To_Change> for the same I have used in the registry. It has solved my problem with broken pipe error.

I created an app game that runs perfectly on the eclipse emulator. However, when my friends download it in the Google Play Store it crashes on start up. I have attached the crash report from my Google Developer Dashboard, it says the crash is caused by java.lang.ClassNotFoundException but I can't figure out how to fix this. Can you guys please help me? I've been struggling with this for a few days.

One suggestion I have - please check if user sometimes earlier already installed and tested older version of the game, and possibly old corrupted data stay at the device memory. In this case un-installing the app thru app manager, and cleaning-up the related data may help. Good luck!

My firebase console dose not show any data if I go to rules then also it is not showing rules also it is just showing unable to show rules what should I do?
it might seem ridiculous but I have tried to log out and log in but it didn't help so i changed the web browser and it worked
I had the same problem. It was the Ads blocker. Just I disabled it and data showed up.
Be careful of these sneaky extensions.
Hope it helps others.
just goto the RULES option given beside the data in Firebase and change the read,write from false to true and then click simulator and publish it.
I have experienced this problem and try this.
Log out of your Google account.
Close every instance of the browser.
Restart your laptop.
Log into the console.
This has helped me numerous times and it might work for you too.

I followed Google's tutorial for the Java version of App Engine and when I ran it on my machine it would work fine at localhost:8888/guestbook and all it displayed was Hello, World. However when I deployed it and then accessed it through app-name.appspot.com/guestbook, it gives me a 500 error.
Here's the GuestbookServlet code: http://pastebin.com/LrAjXjW4
web.xml and appengine-web.xml contents: http://pastebin.com/UYFw3ChZ
I'm really sorry if this is a noob mistake and easily found by searching but I looked around for half a day and still couldn't find an answer.
I'll post more code if necessary but its basically the first tutorial of AppEngine in Java
Thanks
Sounds like you're using Java 7, which App Engine doesn't support. Recompile with JDK6 and it should clear up.
