Sebb commented on MCOMPILER-537:
--------------------------------
AFAICT the compiler does produce these messages when run stand-alone; it looks
like Maven suppresses them.
I ran the command shown in the -X output, and got the following:
Note: Some input files use or override a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
(The associated file names are not shown).
This was with
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /opt/apache-maven-3.6.3
Java version: 19.0.2, vendor: Oracle Corporation, runtime:
/Library/Java/JavaVirtualMachines/jdk-19.0.2.jdk/Contents/Home
Default locale: en_GB, platform encoding: UTF-8
OS name: "mac os x", version: "12.6.6", arch: "aarch64", family: "mac"

> Further to MCOMPILER-491, there is another difference between forked and

> shown in the forked case.
> For example:
> $ git clone https://gitbox.apache.org/repos/asf/commons-compress.git
> --single-branch --branch commons-compress-1.22 --depth 1
> $ cd commons-compress
> $ mvn clean compile
> ...
