---------------------------------------
Summary: 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
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
