Build Flatpak from Java application

I'm currently working on DXVKoTool, a Compose application built with Kotlin.
As I want it to be easily available on the Steam Deck, I try to build a Flatpak off it.
Basically what I wanted to do is packaging it (with jpackage) and use the built binaries when building the Flatpak.
My building process would look like this:
./gradlew packageAppImage
flatpak-builder build/release/main/flatpak dev.datlag.DXVKoTool.yml --force-clean
The packageAppImage command produces an output like this:
{project-dir}
|-build
|-release
|-main
|-app
|-DXVKoTool
|-bin
| |-DXVKoTool {executable}
|-lib
|-{resources, binaries, etc.}
However building the Flatpak is somehow driving me crazy and I'm not sure what's wrong.
My flatpak build YAML file:
app-id: dev.datlag.DXVKoTool
runtime: org.freedesktop.Platform
runtime-version: '21.08'
sdk: org.freedesktop.Sdk
command: DXVKoTool
modules:
- name: dxvkotool
buildsystem: simple
build-commands:
- mkdir -p /app/lib/
- install -Dm755 ./build/release/main/app/DXVKoTool/bin/DXVKoTool /app/bin/DXVKKoTool
- cp -R ./build/release/main/app/DXVKoTool/lib/* /app/lib/
sources:
- type: file
path: ./build/release/main/app/DXVKoTool/bin/DXVKoTool
- type: dir
path: ./build/release/main/app/DXVKoTool/lib/
When I run the flatpak-builder command, it's stopping with the following error:
Emptying app dir 'build/release/main/flatpak'
Downloading sources
Starting build of dev.datlag.DXVKoTool
Cache hit for openjdk, skipping build
Cache miss, checking out last cache hit

When I change the config to the following:
app-id: dev.datlag.DXVKoTool
runtime: org.freedesktop.Platform
runtime-version: '21.08'
sdk: org.freedesktop.Sdk
command: DXVKoTool
modules:
- name: dxvkotool
buildsystem: simple
build-commands:
- mkdir -p /app/lib/
- install -Dm755 DXVKoTool /app/bin/DXVKoTool
- cp -R lib/* /app/lib/
sources:
- type: file
path: ./build/release/main/app/DXVKoTool/bin/DXVKoTool
- type: dir
path: ./build/release/main/app/DXVKoTool/
The building works but after installing the outcome it doesn't start with this error:
bwrap: execvp DXVKoTool: No such file or directory
Would be nice if someone can help me building the Flatpak.

Gitlab CI/CD running fine on local but not on gitlab

I am trying to build a gitlab CI/CD pipeline on my java maven project. I tried all the stages on my local machine and they are passing successfully but when I try the same things on gitlab repo it is throwing error. I tried almost every solution and gone through numerous posts to resolve the errors but to no use. Here is my yml content:
image: maven:3.5-jdk-8
variables:
MAVEN_CLI_OPTS: "-s .m2/settings.xml --batch-mode"
MAVEN_OPTS: "-Dmaven.repo.local=.m2/repository"

script:
- mvn $MAVEN_CLI_OPTS test -B
The stage validate and compile are running fine but I am getting warnings in sonar check and spotbugs sast. The same is running fine on my local.
In the sonarqube check the error is:
Error resolving version for plugin ' -Dsonar.host.url=http://XX.XX.XXX.XXX' from the repositories [local (/builds/XX.XX.XXX.XXX/.m2/repository), central (https://repo.maven.apache.org/maven2)]: Plugin not found in any plugin repository -> [Help 1]

and for the spotbugs-sast warning the error is:
[FATA] [Find Security Bugs] ▶ lstat /root/.m2/repository: no such file or directory
I have spent numerous hours resolving this and waiting for the project to compile successfully with all the stages but every time I was disappointed. Please help. I appreciate your time.

Maven recognized the String -Dsonar.host.url=http://XX.XX.XXX.XXX as a plugin/goal that it needs to resolve.
This is caused by the \ in your script.
Instead of:
mvn sonar:sonar \ -Dsonar.projectKey=XX.XX.XXX.XXX \ -Dsonar.host.url=http://XX.XX.XXX.XXX \ -Dsonar.login=XX.XX.XXX.XXX -X
try:
mvn sonar:sonar -Dsonar.projectKey=XX.XX.XXX.XXX -Dsonar.host.url=http://XX.XX.XXX.XXX -Dsonar.login=XX.XX.XXX.XXX -X
I assume that you copied that command from a format like this:
mvn sonar:sonar \
-Dsonar.projectKey=XX.XX.XXX.XXX \
-Dsonar.host.url=http://XX.XX.XXX.XXX \
-Dsonar.login=XX.XX.XXX.XXX -X
In bash the \ must be at the end of the line if the command contains a linebreak so it's recognized as one command.
But you need to remove it if you convert it to one line.

how can i solve this error please?

You are using a base image which has gradle by itself. So, you don't need to copy gradle explicitly. Just remove ./ from gradle RUN.
RUN gradle build || return 0
COPY . .
RUN gradle clean build

Travis CI Android build keep failing with gradlew no such file

my travis ci build keeps failing with,
$ chmod +x /.gradlew
chmod: cannot access ‘/.gradlew’: No such file or directory
The command "chmod +x /.gradlew" failed and exited with 1 during .
I tried all the suggestions, different yml files but cant get rid of this error.
My travis yml is on root directory, the here is my folder structure
root: /src .gitignore .travis.yml
src: /client /server
client: /app /gradle/wrapper build.gradle gradle.properties gradlew gradlew.bat settings.gradle
Here is my travis.yml
sudo: false
language: android
jdk:
- oraclejdk8
android:
components:
- tools
- platform-tools

- addon-google_apis-google-19
before_install:
- chmod +x /.gradlew
script:
- "/.gradlew clean build"
notifications:

and here is my build.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {

}
}
task wrapper(type: Wrapper) {
gradleVersion = '2.3.3'
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Any suggestions? Thanks

To debug this you could change the before_install section to print current directory and list its contents.
before_install:
- pwd
- ls -la
- chmod +x /.gradlew

Add this .yml file
- name: Check Directory
run: - pwd
- ls -la
- cd android && chmod +x ./gradlew
- name: Build Command
run: cd android && chmod +x ./gradlew
