pzygielo opened a new issue, #11850:
URL: https://github.com/apache/maven/issues/11850
### New feature, improvement proposal
1. Given the command:
```
mvn -V -q help:help
```
2. The command, with `.mvn/maven.config`:
```
-ntp
--threads
1C
```
gives:
```
Apache Maven 3.9.14 (996c630dbc656c76214ce58821dcc58be960875b)
...
Java version: 21.0.10, vendor: Red Hat, Inc., runtime: ...
Default locale: en_GB, platform encoding: UTF-8
OS name: "linux" ...
```
It's fine.
3. The same command with `.mvn/maven.config`:
```
-ntp
--threads
1
```
gives:
```
Apache Maven 3.9.14 (996c630dbc656c76214ce58821dcc58be960875b)
...
Java version: 21.0.10, vendor: Red Hat, Inc., runtime: ...
Default locale: en_GB, platform encoding: UTF-8
OS name: "linux" ...
[ERROR] Error executing Maven.
[ERROR] Invalid threads value: ' 1'. Supported are integer values.
```
4. Command could be also used w/o `maven.config` like so:
```
mvn -V -q help:help -T ' 1C' # a
mvn -V -q help:help -T ' 1' # b
```
which also works for case _a_ and doesn't for _b_.
5. Having leading or trailing space in option gives something like
```
org.apache.commons.cli.ParseException: Unrecognized maven.config file
entries: [ -ntp ]
```
or
```
Unable to parse maven.config file options: Unrecognized option: -ntp
```
which might come from `commons-cli`.
But as parsing threads value is done in Maven - could it be always trimmed
first?
This is for `Float.parseFloat` (`valueOf`):
https://docs.oracle.com/javase/8/docs/api/java/lang/Float.html#valueOf-java.lang.String-:
> Leading and trailing whitespace characters in `s` are ignored. Whitespace
is removed as if by the
[String.trim()](https://docs.oracle.com/javase/8/docs/api/java/lang/String.html#trim--)
method; that is, both ASCII space and control characters are removed. **The
rest** of `s` should constitute a FloatValue ...
But nothing like that happens in `Integer.parseInt`.
