Maven 4 flavour does not use full terminal

[mthmulders]

One of the many things I like in Maven 4 (alpha) is the longer line width. As an example, see the first few lines of any build:

Apache Maven 4.0.0-alpha-8-SNAPSHOT (36db1e35cac5e8c72bf0c795dd08756e50079e05)
Maven home: /opt/homebrew/Cellar/maven-snapshot/4.0.0-alpha-8-20230719.153755-14/libexec
Java version: 17.0.7, vendor: Eclipse Adoptium, runtime: /Library/Java/JavaVirtualMachines/temurin-17.jdk/Contents/Home
Default locale: en_NL, platform encoding: UTF-8

[INFO] Scanning for projects...
[INFO] --------------------------------------------------------------------------------------------------------------------------

[INFO]

The equivalent with mvnd however does not leverage the full terminal width:

Apache Maven Daemon (mvnd) 1.0-m7 darwin-aarch64 native client (b2ef5d81997adbcdb72dc8c5603722538fa641fe)

In both cases, I ran the validate phase and added -V to print the version of Maven (Daemon).

Nice catch. I think the reason is that mvnd needs to provide a custom MessageBuilderFactory with an implementation that would do something similar to

maven-mvnd/daemon/src/main/java/org/apache/maven/cli/MvndHelpFormatter.java

Lines 151 to 159 in 7d9a39b

	private static int getTerminalWidth() {
	int terminalWidth;
	try {
	terminalWidth = Environment.MVND_TERMINAL_WIDTH.asInt();
	} catch (Exception e) {
	terminalWidth = 80;
	}
	return terminalWidth;
