There are two methods of file deletion
1. file.delete()
2. file.deleteOnExit()
The file is not deleted and returns false and have tried both the cases. Now I need to find the actual reason why the deletion has not happened
How to find out the reason? Is any log needs to be enabled or trace out the issue?
There are more than two methods of deleting a file!
You can use the utility class java.nio.file.Files:
Files.delete(path);
will throw an IOException that will tell you the reason it failed.

I want to write Java code that can read variables and call methods from another .jar file without importing it, like forge in Minecraft. How can I do it?
I loaded the .jar file with URLClassLoader but I couldn't call the methods and read the variables.

I am getting an error in my project, No variants found for 'app'. Check build files to ensure at least one variant exists.

your gradle build may have failed. make sure you have build.gradle, open the file and do Sync now, look for errors to tell you what is wrong.

java.lang.ClassNotFoundException: org.aspectj.weaver.tools.PointcutParser
I use aspect in my project, and when I run it, this exception throws.
But When I remove my aspects, this issue disappears.
Can anyone help with this issue?
Thanks!!!
You need aspectjtools to your classpath

http://mvnrepository.com/artifact/org.aspectj/aspectjtools
It would be quite easy to add it as maven-dependency with compile-scope

So I am getting a NullPointerException on the same line of code no matter how I change it. Even if I put a blank line there is still the same error on same line. Has anyone else had this happen? I'm pretty confused as to what could cause this.
edit: Should have mentioned I wasn't planning on posting my hundreds of lines of code as the error is always on line 317. Just trying to figure out if anyone else has had a similar problem and what the cause was. Also yes I have checked that I am debugging and running correct code.
It sounds to me like there is an issue with your environment. I would step back and make sure you are running or debugging the code you think you are.
