I have a ROS2 package which is failing to build. I'm following the ROS2 "Setting Up a Robot Simulation (Webots)" tutorial, and when I got to section 6 "Modify the setup.py file", I changed my file like so:
from setuptools import setup
from glob import glob
package_name = 'ad_boxtra'
setup(
name=package_name,
version='0.0.0',
packages=[package_name],
data_files=[
('share/ament_index/resource_index/packages',
['resource/' + package_name]),
('share/' + package_name, ['package.xml']),
('share/' + package_name, glob('launch/*.py')), # include all launch files
('share/' + package_name, glob('resource/*.urdf')), # include all webots-related resource files
('share/' + package_name + '/webots_simulation/worlds', # include desired webots worlds
['worlds/adboxtra_2022_simplified.wbt']),
],
install_requires=['setuptools'],
zip_safe=True,
maintainer='redacted',
maintainer_email='redacted',
description="redacted",
license='MIT License',
tests_require=['pytest'],
entry_points={
'console_scripts': [
'my_robot_driver = ad_boxtra.my_robot_driver:main',
],
},
)
I then ran colcon build with debug info from the root of my workspace and got:
user#host:~/my_ws $ colcon build --packages-select ad_boxtra --event-handlers console_direct+

Why is this colcon build failing? If it helps, here's my directory tree:

I did observe that in the install/ directory of my workspace, it seems that share/ad_boxtra/webots_simulation/worlds/ exists, but there's no .wbt files inside it. I don't know why this is though:

From the Python documentation:
data_files specifies a sequence of (directory, files) pairs in the following way...
You wrote
('share/' + package_name + '/webots_simulation/worlds',['worlds/adboxtra_2022_simplified.wbt']), but it should be ('share/' + package_name + '/webots_simulation/worlds',['adboxtra_2022_simplified.wbt']).
You could check the build folder too. Just delete build and install and try again. It could be that.
OK so I know how to remove class files from all the jars under a dir. But, now I have different layer from a docker image, each layer is a tar file, and in the tar file there are the jar files.
Can I remove the class files from the jar files, packaged in tar files?

So you ask me why?
Well, did you hear people talking about log4j recently? :) I am doing this right now: log4j vulnerability check: how to quickly detect if log4j is used, in mavevn/in an image? "mvn dependency:tree" does not give a full picture
If someone can tell me how to remove these classes from jib maven plugin, that's better. They are from a base image and I doubt we could do that, though.
I have installed cjson using Lua Rocks locally.
luarocks install --local lua-cjson
But I cannot access the module.
> require('cjson')
stdin:1: module 'cjson' not found:
Packages were installed in to ~/.luarocks. Following is the file structure

What are the environment variables that should be in place for Lua to be able to find the packages?
luarocks path prints everything that should be added
➜ ~ luarocks path
export LUA_PATH='/usr/share/lua/5.4/?.lua;/usr/share/lua/5.4/?/init.lua;/usr/lib/lua/5.4/?.lua;/usr/lib/lua/5.4/?/init.lua;./?.lua;./?/init.lua;/home/s1n7ax/.luarocks/share/lua/5.4/?.lua;/home/s1n7ax/.luarocks/share/lua/5.4/?/init.lua'
export LUA_CPATH='/usr/lib/lua/5.4/?.so;/usr/lib/lua/5.4/loadall.so;./?.so;/home/s1n7ax/.luarocks/lib/lua/5.4/?.so'

It just prints them NOT run them. So that needs to be ran. I added following line to init script to add the path at system boot
eval $(luarocks path)
I have the following folder structure:
> tree -L 3
├── pom.xml
├── src
│ ├── main
│ │ ├── java
│ │ └── resources
│ └── test
│ ├── groovy
│ └── resources
I tried to build docker image containing those folders together with files using the following Dockerfile:
FROM jamesdbloom/docker-java8-maven
USER root
RUN mkdir src
ADD ./src/* ./src/
ADD pom.xm
However, the structure in docker image is different. Particularly, I can no longer find main and test folders.
$ tree -L 3
.
├── pom.xml
├── src
│ ├── groovy
│ │ └── com
│ ├── java
│ │ └── com
│ └── resources
│ ├── ext_sample_input.json
│ ├── hist_sample_input.json
│ └── sample_input.json
Why is it so?
From official documentation:
Note: The directory itself is not copied, just its contents.
Change your ADD statement to:
ADD ./src ./src/
I have some old tweak which doesn't work on iOS 8.4 and I wanted to debug it and possibly fix it. I am in no way good with writing tweaks, this was something I did for a friend and me and people used it since I published it on BigBoss.
Anyway at the time, I did not have OS X device and I written everything on iPhone using vi over ssh and then I compiled it on iPhone with Theos.
Now I have OS X device and I wanted to import this into Xcode. Is this even possible? If so how can I do this in most easiest way? I already have iOSOpenDev. Here is folder tree:
