Gradle Copy Task causes file permission issue - linux

Question

Background
I have a JetBrains Plugin that I am developing. Recently, I moved from a Windows to a Ubuntu system. I am trying to set up everything correctly as before. Note: I am fairly new to Linux.
Issue
I am having an apparent file permission issue (as can be seen in the error section of this question) when I ran the following Gradle script. Note: Whenever I build the project, this Gradle script is automatically called. It also worked correctly on Windows.
If I comment out the copy{...} closure then everything works correctly. I just need to manually copy over the required file.
tasks.create(name: "copyJar_v${project['version']}") {
group GROUP_CHROMATERIAL
def mostCurrentJarFile = "ChroMATERIAL-${project['version']}.jar"
// comment this out and there are not errors, but I need to do this copy manually
copy {
into '/' // Copy into project's root folder
from 'build/libs', {
include mostCurrentJarFile
rename mostCurrentJarFile, 'ChroMATERIAL.jar'
}
}
}
Error
FAILURE: Build failed with an exception.
* Where:
Build file
'/home/ciscorucinski/IdeaProjects/ChroMATERIAL/ChroMATERIAL/build.gradle' line: 100
* What went wrong:
A problem occurred evaluating project ':ChroMATERIAL'.

What I tried
I have been using the UI to modify the file permissions of the Plugin Project Folder within IdeaProjects.
I gave everyone Create and delete files permissions and I Change Permissions for Enclosing Files...
Everyone has Read and write access to files and Create and delete files access to folders.
Clicked Change
Run the Gradle script again ... same error message
Thoughts
It appears that Linux is not letting Gradle modify these files. I can comment out the code and do everything myself, but I need to allow Gradle to have higher control. Don't know how though.
I notice that when I go back to Change Permissions for Enclosing Files... the shown permissions are not what I selected! Others has Read-only access to files and Access files access to folders. I don't know if this is common Ubuntu behavior, a bug, or something else.
It would be nice to know how to give as restrictive as possible access while fixing this.

Answer 1

Well, it is true -- you cannot (and should not) copy files into the Root folder in a linux box. You could if you ran the script as sudo, but that is a bad idea.
Edited
Since you want to copy to the root of the project, you can use ${projectDir} or ${rootDir}.
Also, you should be able to do this without the hassle of a closure -- and it makes your script cleaner, IMHO -- by using the built in Copy task:
task copyClientLoc(type: Copy) {
from "build/libs/"
into "${rootDir}"
include "ChroMATERIAL-${project['version']}.jar"
fileMode = 0644
}
