Issue Installing java - java

so i was installing java and my pc decided to shut off before it could finish, i don't have java anymore, and now when i try to open the installer it never opens, i have tried using CCleaner to clean the registry, i have tried installing in safe mode, someone told me to check the checksum to make sure the file isn't corrupted and its not, i have tried the offline and online installers with no luck
i have been trying to solve this for a week with no luck =P was hoping you guys could help

You could try deleting the location it was installing to and then reinstalling.

Issue with Reinstalling Eclipse After upgrading hard drive

I am a programming student that recently upgraded the hard drive in my laptop through a secondary service. This service was able to save and transfer over most files, but was unable to migrate over specific program files.
When trying to reinstall Eclipse I have encountered some major issues and problems I am looking to hopefully get help with.
The first issue is that through the Eclipse installer, when trying to install eclipse it would try to look for the previously used user file and spew out 100s of error messages when this failed. A workaround to get eclipse actually installed was to change the bundle pools to off.
The second and most major issue is that eclipse does not seem to recognize or have any in build libraries, as it does not even recognize what a string is. I have the JDK and JRE installed but when trying to compile is tells me that java has been installed incorrectly (which would make sense given my hack job of installing it).
Any help would be greatly appreciated. I have never had so much difficulty trying to simply install something.
Try deleting .m2 folder present inside C:/Users/<User Name>/.m2 and then reinstall Eclipse.

Eclipse won't load: failed to find a main class

I am trying to download Eclipse onto my flash drive so that it can support itself if I try to use Eclipse on a computer that does not have a JDK/JRE installed and/or I do not have the permissions to install one.
I am able to download it onto the flash drive and run it fine, but the problem arises when I try to make it self-sufficient by downloading a JDK for Eclipse to use on the drive. I have tried many different solutions (yes, I am aware of the abundance of "why is eclipse telling me it cant find main class" questions), but none of them apply to me. I followed this tutorial in my endeavors, but when I run the batch file it comes up with the standard Failed to find a Main Class in "F:\eclipse\\plugins/org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar.
I know the \\ looks a bit out of place, but I know that's not the problem since I've tried editing the eclipse.ini file to fix the path but it gives the same error (just with F:\eclipse\plugins\org.[...].jar instead)
I'd really appreciate any help anyone could give. Thanks!
Eclipse has required Java 8 or newer since the Neon release, in 2016. Update your version of Java.

Unable to save settings : IntelliJ IDEA

I use IntelliJ IDEA 15 and have a problem with the auto-saving. For example I make a new configuration, e.g. Show the line number. When I close IntelliJ and reopen my IDE, it doesn't save my configuration and shows me this message:
Unable to save settings : Failed to save settings . Please restart IntelliJ IDEA
I get this too (IntelliJ 15.0.5), but only when the "Markdown support" plugin is used. Once a .md file is visualised the error starts appearing.
For future reference current version: 2016.1.20160405.143
Not a very solution-oriented post, but maybe this can help someone further pinpoint the source of the error.
This workaround allows you continue using "Markdown Support".
Uninstall the latest version of "Markdown Support" and install version "8.0.0.20160127.143.1" from https://plugins.jetbrains.com/plugin/7793?pr=idea. Everything works fine.
I was receiving the error with:
IntelliJ v15.0.6
"Markdown support" plugin version 2016.1.20160405.143
I uninstalled the Markdown support plugin (IntelliJ IDEA > Preferences... > Plugins > Markdown support), restarted IntelliJ, and am now able to save without error.
I have tried everything from this SO thread but it did not work. I solved it by deleting the .idea folder from my project's Windows path and then restarting intellij.
This can also happen when the disk drive where the currently opened project is stored is full (0 bytes left on device). The system tries to write to the .idea folder but cannot, so it gives the same error as if there were no access rights.
This happened to me as there was a process writing to disk in the background until it was full.
I delete this file : .IntelliJIdea
When I launch ./idea I should reconfigure all IntelliJ system (config/ extention/ theme/ licence ...)
So It's okay now but I think is not a good solution ...
Workaround for Windows users.
My installation is located in:
"C:\Program Files\JetBrains\phpstorm"
The location gives it problems with the saving of files. (probably to do with user rights and UAC, not totally figured out what rights the folder needs, but for easy resolving I removed and reinstalled Phpstorm to
"C:\development\phpstorm" and it resolved the issue.
For those who have a simular issue on windows machines:
I have applied the "hidden" property for the .[IntelliJ-Produkt][Version] folder in Users/[Username] folder. This was causing the issue. Don't do that.
I encountered this problem when I open up IDEA for the first time after copying the old config files backed up with my Live CD USB before reinstalling my Ubuntu. I think it is because I copied the files from the old OS and to the new OS as root, so the ownership of the folder is changed. Now when I want to write to it as another user, it blocks me from doing it.
Change the ownership to your user and change permission to add write solves it. You use chown and chmod.
On OSX, I've uninstalled PhpStorm, and then have installed it again, always by using the JetBrains TOOLBOX.
Hope it helps!
Windows Defender was the issue
Windows defender has a protection component called ransomware protection (details: https://www.makeuseof.com/tag/protect-ransomware-windows-defender/)
This restricts folder access (for selected folders) to some programs only.
Add Webstorm to allowed applications
Excerpt is below. Full guide with pictures are here: https://www.windowscentral.com/how-allow-blocked-apps-ransomware-protection-windows-10-october-2018-update
Open Windows Security.
Click on Virus & threat protection.
Under "Ransomware protection," click the Manage ransomware protection option.
Click the Allow an app through Controlled folder access option.
Click the Add an allowed app button.
Click the Recently blocked apps option.
Click the + (plus) button for the app you trust and want to allow.
Click the Close button.
I faced the same issue today and it might help some people if above solutions cant help. I am using dual boot system. Win 8 and Kubuntu. I got this problem with my intellij installed in Kubuntu. I realized my project was in a NTFS partition which was marked as READ ONLY. This happens sometimes when you shutdown windows and start computer into your linux.
Solution is to go back to your windows OS and restart it and switch to linux. Also, you could hold shift and press shutdown button, then choose to turn of your pc in the blue menu.
On windows 10 I had the same problem, I ran PhpStorm as administrator which fixed permission issues it had.
Then I restarted PhpStorm without administrator permissions and everything worked fine.
It was a fresh install so no plugins other then the build in ones.
I've encountered this issue multiple times; rebooting my (windows) computer has always worked for me (while restarting Intellij didn't do anything).
It's because you don't have permission to save settings. On my macOS, I set write permission of my project.
I got same error message for InteliJ WebStrorm saying
Unable to save settings
Failed to save settings. Please restart WebStorm
It happened due to permission issue. if you don't have permission to save this message could pop-up. Please make sure you have write permission to the folder you are saving.
I might be late at answering this but I did not see any accepted answers here.
I got a solution to this on other forum.
They suggested to start IntelliJ IDEA as Administrator.
It worked for me.
Hope it helps people who come here searching for answers.
for my Ubuntu, i fixed it by issuing this command.
sudo chmod 777 /path/to/dir

Correct Java dependencies installed for eclipse ADT development

I have eclipse and the ADT bundle correctly installed on my home PC, and tried to install it on my laptop so I can work on my projects on the go. However, I either didn't set the java paths correctly, or installed them in the wrong place, because I can't get a default project to load without errors.
I have correctly:
-Installed the ADT bundle and launched eclipse without errors
-Created a workspace
-Correctly Installed both the jre8 and jdk1.8.0_05 in the location C:\Program Files\Java
I am very new to Android development, and I feel like I was lucky to set up the Java dependencies correctly on my home PC, no such luck this time from what the error look like...
However, when I try to make a basic "Hello world" project, I immediately get the following error:
The container 'Android Dependencies' references non existing library 'C:\Users\userName\workspace\appcompat_v7_3\bin\appcompat_v7_3.jar'
I have tried adding the library, by checking build configurations, but I don't understand fully whats going on to correctly solve the problem. Here is my workspace:
And lastly, I tried checking the build configurations to see that the libraries are, in fact, missing. Or something like that. I am not sure if I should just try to reinstall java and the jdk.
Build configuration:
Anyway, I'm not sure what I deleted, misplaced, uninstalled, or didn't install, but if anyone could point me to a solution I would be very grateful. If anyone has any other questions on my setup I will try and be as thorough as possible. Thank you!
In my experience I have had issues like this if not running eclipse as Administrator. Make sure that you aren't being blocked here.
EDIT: Please note Chris Stratton's concers regarding running an IDE as Administrator, as seen in the comments below.
EDIT 2: In my more recent experience, I have noticed that if I installed the SDK by copying and pasting the contents of the downloaded, compressed, folder to a destination rather than extracting it first, I would be required to run as Administrator. If this is the case, delete the SDK that you copied out of the compressed folder and simply extract the contents of the downloaded compressed folder. I am running Windows 7 so it is likely that this applies to all Windows 7 and 8 OS's.
In another case, I have also seen issues like this if the JRE is installed second rather than first. In this case, a reinstall of the SDK is probably all that is required.

Eclipse "Permission denied" error when trying to launch app

I'm trying to get started creating some apps for Android but I keep running into this Eclipse error:
NAND: could not read
file...android-sdk_r07-windows\android-sdk-windows/platforms\android-7\images/system.img,
Permission denied.
Do you think I should delete the package and re-install? I'm wondering whether it could be a corrupted file, although it says "permission denied" which makes me think not so. I just installed the plugin for Eclipse and created my emulator but I can't run because of this error.
I have googled searched this and could not find a relevant answer. Any help would be greatly appreciated. :)
This looks like file locking in windows. I will download unlocker for windows and check for processes that have lock on the folder you mentioned. What happens when you run emulator in the command line?
The file seems to be locked or otherwise could not be read.
First you could try to run Eclipse as an Administrator (especially if you are running Windows 7, which has stricter file access than XP).
May I suggest that you download Process Explorer http://technet.microsoft.com/en-us/sysinternals/bb896653 and hit Control-F to search for system.img. Then you'll probably find which process is locking up your file. You can kill the handle in the bottom view of process explorer.
If all else fails you can reinstall Eclipse and/or ADT from scratch. Good luck!
I suggest you to log in as a administrator if you are using Windows 7. When you open Eclipse, right-click on the Eclipse icon and select Run as Administrator.
I suggest reading developer.android.com - the section about SDK, ADT is not so big. And then maybe reinstalling the SDK step by step.
The documentation on the Android Developers Site is very helpful. It couldn't hurt to uninstall the SDK and then try a reinstall closely following the directions given on the above link.
dude you should get the latest sdk version.
also you can try checking if your user has full permissions on the sdk fodler as well as eclipse workspace
has same problem. Solved when i changed target from Android to Google API
