Fail to build Micro-XRCE-DDS-Gen

[tieugiang91]

I cloned the source code from Git and also separately cloned IDL-Parser into thirdparty folder from: https://github.com/eProsima/IDL-Parser/tree/9e36ac4b18c8083ac7106761a8a6e908e04ae458 gradle build failed with the following errors: `

The video is error

The requirements "Gradle is an open-source build automation tool, version 7.0 or higher is required." in the doc are wrong, the installation of gradle 7.6 cannot compile Micro-XRCE-DDS-Gen, and the installation method shown in the video installs the 4.4.1 version of gradle, which can successfully compile Micro-XRCE-DDS-Gen. @pablogs9

I have ran into this too. Which version of Gradle should we be using?

ryan@ryan-m93p:~/Documents/ardu_ws/src/gen_ws/Micro-XRCE-DDS-Gen$ gradle --version

------------------------------------------------------------
Gradle 8.0.1

Revision:     68959bf76cef4d28c678f2e2085ee84e8647b77a

Kotlin:       1.8.10
Groovy:       3.0.13
Ant:          Apache Ant(TM) version 1.10.11 compiled on July 10 2021

This does not work, and was installed on Linux Ubuntu 22.04, which I am using ROS2 Humble on.

Is Gradle 8.0.1 the version released with Ubuntu 22.04?

No. It's 4.4.1 https://packages.ubuntu.com/jammy/gradle
