Garret Wilson created MPH-193:
---------------------------------
Summary: Document charset for evaluate goal file output.
Key: MPH-193
URL: https://issues.apache.org/jira/browse/MPH-193
Project: Maven Help Plugin
Issue Type: Improvement
Components: evaluate
Affects Versions: 3.3.0
Reporter: Garret Wilson
I'm using Java 17 on Windows with
`org.apache.maven.plugins:maven-help-plugin:3.3.0`. The
[{{<output>}}|https://maven.apache.org/plugins/maven-help-plugin/evaluate-mojo.html#output]
option allows the evaluated information to be sent to a file. But the
documentation does not say which charset will be used!
I was afraid that you might be using the system default charset (which would be
very bad). But I did a test:
{code:xml}
<properties>
<foo><![CDATA[<bar>touché 😃</bar>]]></foo>
</properties>
…
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-help-plugin</artifactId>
<executions>
<execution>
<id>foobar</id>
<phase>generate-resources</phase>
<goals>
<goal>evaluate</goal>
</goals>
<configuration>
<expression>foo</expression>
<output>${project.build.directory}/foo.xml</output>
</configuration>
</execution>
</executions>
</plugin>
{xml}
It was a huge relief to find that the output file {{foo.xml}} contained the
word "touché" followed by a smiley face emoticon, encoded in UTF-8! This is
good!
It is a huge relief to see that you're encoding the output in UTF-8 and not
some arbitrary, per-system encoding. But this needs to be documented so we'll
know that we can depend on that. Thank you.
