Konrad Windszus commented on MSHARED-815:
-----------------------------------------
To me it seems that the right thing to e.g. escape key "test" with value
{code}
This is a paragraph
This is another paragraph
{code}
is
{code}
test: This is a paragraph
This is another paragraph
{code}
There is a space in line 2!
> Maven Archiver: MavenArchiver.addManifestAttribute does not escape empty
> lines in value

> Key: MSHARED-815
> URL: https://issues.apache.org/jira/browse/MSHARED-815
> Project: Maven Shared Components
> Issue Type: Bug
> Components: maven-archiver
> Affects Versions: maven-archiver-3.4.0
> Reporter: Konrad Windszus
> Priority: Major
>
> According to
> https://docs.oracle.com/javase/10/docs/specs/jar/jar.html#name-value-pairs-and-sections
> {quote}
> Groups of name-value pairs are known as a "section". Sections are separated
> from other sections by empty lines.
> {quote}
> Therefore empty lines in attribute values lead to invalid manifests and must
> somehow be escaped.
> As this is not done by default in {{java.util.jar.Attributes.writeMain(...)}}
> the method {{MavenArchiver.addManifestAttribute(...)}} should either throw an
> exception in case of empty lines given to parameter {{value}} or escape those
> empty lines somehow
