Giedrius Noreikis commented on MDEP-541:
----------------------------------------
We need more flexibility, and {{maven-archiver}} does not allow (at least I
couldn't find a way) to exclude some dependencies from the {{Class-Path}},
which is necessary in our case as we repackage some jars from dependencies into
the final jar (with a help of {{proguard-maven-plugin}}).
> Allow for a space character as a pathSeparator in dependency:build-classpath
> ----------------------------------------------------------------------------

> Key: MDEP-541
> URL: https://issues.apache.org/jira/browse/MDEP-541
> Project: Maven Dependency Plugin
> Issue Type: Improvement
> Components: build-classpath
> Reporter: Giedrius Noreikis
>
> Currently, the {{dependency:build-classpath}} goal does not allow a space
> character to be specified as a {{pathSeparator}}, which is necessary to
> generate {{Class-Path}} values for manifests.
> Because of a check {{isPathSepSet = StringUtils.isNotEmpty( pathSeparator )}}
> in {{BuildClasspathMojo.java}}, the parameter gets ignored in this case, and
> the classpath is built with a default separator.
> The possible workaround is to fix the path with
> {{build-helper:regex-property}}:
> {code:xml}
> <plugin>
> <groupId>org.codehaus.mojo</groupId>
> <artifactId>build-helper-maven-plugin</artifactId>
> <executions>
> <execution>
> <id>fix-classpath-for-manifest</id>
> <phase>prepare-package</phase>
> <goals><goal>regex-property</goal></goals>
> <configuration>
> <name>appClasspath</name>
> <value>${appClasspath}</value>
> <regex>;</regex>
> <replacement xml:space="preserve"> </replacement>
> <failIfNoMatch>false</failIfNoMatch>
> </configuration>
> </execution>
> </executions>
> </plugin>
> {code}
> but a fix would allow for a more straightforward solution.
