[jira] [Commented] (MJAVADOC-489) Javadoc plugin needs to set module path

["Valentin Kovalenko (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MJAVADOC-489?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16240604#comment-16240604 ] 

Valentin Kovalenko commented on MJAVADOC-489:
---------------------------------------------

I believe the "Affects Version/s" should be changed from 2.10.4 to 3.0.0-M1, because according to https://cwiki.apache.org/confluence/display/MAVEN/Java+9+-+Jigsaw 3.0.0-M1 is the minimal version compatible with Java 9 Jigsaw.

[~rfscholte] Could you please also add this issue to the "Related Issues" list for maven-javadoc-plugin in the aforementioned page?

> Javadoc generation fails for Jigsaw modules that depends on other Jigsaw modules:
> {code}
> module c {
>   requires a;
>   requires b;
> }
> {code}
> while javadoc generation succeeds for modules a and b which have no module dependencies javadoc generation fails for module c which has module dependencies
> {code}
> MavenReportException: Error while generating Javadoc: 
> [ERROR] Exit code: 1 - /Users/user/git/jigsaw/src/main/java/module-info.java:3: error: module not found: a
> [ERROR]   requires a;
> [ERROR]                                ^
> [ERROR] /Users/user/git/jigsaw/src/main/java/module-info.java:4: error: module not found: b
> [ERROR]   requires b;
> [ERROR]                                ^
> [ERROR] 
> [ERROR] Command line was: /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/bin/javadoc @options @packages @argfile
> [ERROR] 
> [ERROR] Refer to the generated Javadoc files in '/Users/user/git/jigsaw/target/apidocs' dir.
> {code}
> The issue seems to be that the javadoc plugin only ever sets {{-classpath}}. The javadoc plugin would have to set {{--module-path}} like the compiler plugin does.
