When executing the Maven install command in MyEclipse, an error of "Failed to read artifact descriptor for xxx:jar" is reported. This may be due to an error in the file during the download process. In fact, when you use some compression software such as RAR to open these jar packages, it will prompt that the jar packages are damaged.
Solution: Delete the relevant jar package from the local maven library, then right-click the project, Maven4MyEclipse->Update Project, and select "Force Update Of Snapshots/Releases" in the pop-up dialog box
Then click "OK". This will re-download the jar package.
