Kai Hofmann created MJAVADOC-673: ------------------------------------ Summary: Generating wrong commandline option for javadoc tool when using Java9+ modules Key: MJAVADOC-673 URL: https://issues.apache.org/jira/browse/MJAVADOC-673 Project: Maven Javadoc Plugin Issue Type: Bug Components: javadoc Affects Versions: 3.2.0 Environment: MacOS, Window, Linux, Java 11.0.10 +
With older java versions like 11.0.3 you will got more errors! Reporter: Kai Hofmann When you checkout my open source [TemplateEnginel|https://github.com/PowerStat/TemplateEngine] and simply run {code:java} mvn javadoc:javadoc {code} you will get the following error message: {noformat} [INFO] <<< maven-javadoc-plugin:3.2.0:javadoc (default-cli) < generate-sources @ templateengine <<< [INFO] [INFO] [INFO] --- maven-javadoc-plugin:3.2.0:javadoc (default-cli) @ templateengine --- [INFO] No previous run data found, generating javadoc. [INFO] Loading source file D:\work\eclipse\java\github\TemplateEngine\src\main\java\module-info.java... 1 error [ERROR] Error while creating javadoc report: Exit code: 1 - error: module not found: de.powerstat.phplib.templateengine Command line was: cmd.exe /X /C "D:\Programme\Java\jdk-11.0.10\bin\javadoc.exe @options @packages @argfile" Refer to the generated Javadoc files in 'D:\work\eclipse\java\github\TemplateEngine\target\site\apidocs' dir. org.apache.maven.reporting.MavenReportException: Exit code: 1 - error: module not found: de.powerstat.phplib.templateengine Commandline was: cmd.exe /X /C "D:\Programme\Java\jdk-11.0.10\bin\javadoc.exe @options @packages @argfile"Refer to the generated Javadoc files in 'D:\work\eclipse\java\github\TemplateEngine\target\site\apidocs' dir. [...]{noformat} Now go to *target/site/apidocs* There you could run the generated script by *javadoc.bat*|*sh* Which results in the same error! Please note that the subdirectory *src/de.powerstat.phplib.templateengine* is empty. Now open the *options* file and remove the following lines: {code:java} --module-source-path 'D:/work/eclipse/java/github/TemplateEngine/target/site/apidocs/src' {code} Run the *javadoc.bat*|*sh* again. Now the error {noformat} error: module not found: de.powerstat.phplib.templateengine{noformat} is gone. And the javadocs are generated as expected! So for me it looks like the generated --module-source-path option for the javadoc command is wrong in this (and maybe other) context(s)! The generation happens in org.apache.maven.plugins.javadoc.AbstractJavadocMojo around line 5316. Because of the complexity of this code and it's context (maven Reactor) I am not able to provide a patch for this. But hopefully you could fix this fast, because it is a real blocker that makes maven javadoc generation for java 9+ modules imposible. -- This message was sent by Atlassian Jira (v8.3.4#803005)
