Java Problems with a fresh install

Development Tools IDE 1.x
1

Hello,
I am slowly progressing past the basics but am totally perplexed as I have just set up on old laptop with Win7 and have just installed Java and the latest Win7 version of Arduino IDE (after the windows and drivers).
Anyway, after setting up my libraries I tried a sketch and got Java errors so I went back to basics and plugged in my genuine Uno with the Blink sketch and still get the Java errors. Any help would be greatly appreciated ...

Error messages are as follows;

Arduino: 1.8.13 (Windows 7), Board: "Arduino Uno"

Sketch uses 924 bytes (2%) of program storage space. Maximum is 32256 bytes.

Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

An error occurred while uploading the sketch

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Hi @stevetobias. Please try the fix described in this Help Center article:

I was reading through some other Java related error posts and found that deleting everything in the \Arduino15\ directory except the preferences.txt did the trick. Actually I did not delete everything at first, I just moved them to another folder in my downloads directory but they will be deleted now. After doing this I just needed to reinstall the boards but they were easy because the prefrences.txt still had the JSON links so job done.

Sorry I did not investigate further before posting but on the flip side I hope this can help someone else in the future.
Also after uploading a sketch I get some very detailed information about the board (have never had this before).

additional details as follows;

No need to apologize. This is a very confusing error that should never occur under normal circumstances. Thanks for taking the time to post an update.

stevetobias:
Also after uploading a sketch I get some very detailed information about the board (have never had this before).

This is controlled via the "Show verbose output during: upload" setting in the Arduino IDE's File > Preferences.

Even though I typically recommend against having the "Show verbose output during: compilation" setting enabled (because the extra output it provides is not generally useful), I do recommend always leaving the verbose upload output enabled because it's useful as a progress indicator during successful uploads and useful for troubleshooting of failed uploads.
