Cross-repository Maven

Currently, Maven repositories follow a problematic centralised model. For example, the integrity of the software artifacts is checked by using digests that are located on the same directory as the artifact itself. Given that the verification of digital signatures currently implies additional work by the user, the vast majority of builds never check those signatures and rely on the digests.

This proposal describes how the implementers of Maven clients and repository managers could use a multi-repository model, which would give more choice to users while improving security.

This proposal only applies to releases, not snapshots. The basic idea is to deploy release artifacts to multiple repositories, then put the URLs of the other servers as metadata in the groupId/artifactId directory of each repository, and later use the additional Maven servers for increased reliability (e.g. using digests coming from a different server than the artifact).

This proposal is backwards-compatibl

Changing the author of a commit is often useful when backporting commits in a project fork (e.g. applying Batik commits to EchoSVG). For example, to change the author of the last two commits ("1" and "2"), first run:

git rebase -i HEAD~2

In the subsequent edit session, change the commands from pick to e. Then run

git commit --amend --author="Commit 1 Author <commit-1-author@example.com>" --no-edit

Compile `module-info` separately in Gradle

To make projects compatible with both Java 8 and modular JDKs, a popular strategy is to compile the project so it produces Java 8 bytecode, and separately compile the module-info.java file targeting a modular JDK version.

The Apache Maven documentation includes an example of how to achieve that, but the Gradle user guide lacks it. This document presents an approach that could be included in a convention plugin, and requires Gradle 7 or higher (you could try to adapt it to Gradle 6.x by explicitly enabling inferModulePath in

Compact CSS media rules: the `@assign` mechanism

Justification

As mentioned in my gist about a CSS switch-like function, authors would like to have a mechanism for less verbose CSS @media rules, as expressed in CSSWG's issue 5009.

In that issue a possible new syntax (with a few variants) is suggested, with authors specifying stacked property values that

A switch-like function for CSS

Rationale

In CSS, @media rules are useful but may lead to some unwanted verbosity and maintenance issues. Although var() values are of help, one often has to either duplicate some rule structure or proliferate custom properties that are intended to be used at specific places. That's what CSSWG's issue 5009 is about.

Due to that, sometimes authors would prefer to specify values at the place where they are going to be used in the most common

Install additional commands on Git Bash (Windows 10)

This assumes that your Git Bash is using MSYS instead of Cygwin (look at the output of uname -o if you are in doubt). If you are using Cygwin, please refer to standard Cygwin procedures.

Open http://repo.msys2.org/msys/x86_64/ (or one of the mirrors at https://github.com/msys2/MSYS2-packages/blob/master/pacman-mirrors/mirrorlist.msys) and download the commands that you want to add.
Extract the content of the package that you want to install to a working directory. For example,

    mkdir tmp
    cd tmp
 tar xf ../libzstd-1.4.5-2-x86_64.pkg.tar.xz

Maven dependency version ranges

Introduction

Java:tm: projects generally depend on other projects, and those dependencies are detailed in the file that describes how to build the project, often the Maven POM.

The build process needs to know which version or versions of the dependencies are required to succeed, and projects often specify a single, fixed version, perhaps the same one that was used when the project's code was edited with the help of an IDE. In the Maven POM, this is done by introducing a line like:

1.7.28

	## Store in Documents/PowerShell

	# File hashes
	function md5sum { Get-FileHash -Algorithm MD5 $args }
	function sha1sum { Get-FileHash -Algorithm SHA1 $args }
	function sha256sum { Get-FileHash -Algorithm SHA256 $args }

	# Equivalent of bash `ll` alias
	function ll { Get-ChildItem -Force @args }
