> Key: MJAVADOC-581
> URL: https://issues.apache.org/jira/browse/MJAVADOC-581
> Project: Maven Javadoc Plugin
> Issue Type: Bug
> Components: javadoc
> Affects Versions: 3.0.1
> Reporter: Garret Wilson
> Priority: Critical
>
> This is a critical bug that breaks the build. I originally posted this [on Stack Overflow|https://stackoverflow.com/q/53449049/421049] but got no response.
> I'm using OpenJDK 11 on Windows 10. I have a very simple POM, for a single Java file, that generates Javadocs. Here is an extract:
> {code:xml}
> <properties>
> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
> <maven.compiler.source>11</maven.compiler.source>
> <maven.compiler.target>11</maven.compiler.target>
> </properties>
> <build>
> <plugins>
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-javadoc-plugin</artifactId>
> <version>3.0.1</version>
> <executions>
> <execution>
> <goals>
> <goal>jar</goal>
> </goals>
> </execution>
> </executions>
> </plugin>
> </plugins>
> </build>
> {code}
> Strangely just running {{mvn clean package}} causes an error:
> {noformat}
> [ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:3.0.1:jar (default) on project foobar: MavenReportException: Error while generating Javadoc:
> [ERROR] Exit code: 1 - javadoc: error - cannot read Input length = 1
> [ERROR]
> [ERROR] Command line was: C:\bin\jdk-11\bin\javadoc.exe @options @packages
> {noformat}
> In {{target/apidocs}} there are only three files: {{javadoc.bat}}, {{options}}, and {{packages}}. The {{options}} file is the most interesting. It explicitly says {{UTF-8}} everywhere, as it should. But look at these lines:
> {noformat}
> -sourcepath
> C:/projects/li��o 1/src/main/java
> {noformat}
> This project is in {{C:\projects\lição 1}}. It appears that somewhere along the chain Java or Maven or the Javadoc plugin didn't correctly convert the directory name to UTF-8.
> Sure enough; when I renamed the directories in Windows to remove non-ASCII characters, {{mvn clean package}} worked just fine.
> This would seem like a blatant bug; once Maven starts, everything should be UTF-8 throughout.
> One [answer on Stack Overflow|https://stackoverflow.com/a/53528778/421049] gives you a hint of what's going wrong.
> In any case, I consider this to be a huge bug related to fundamental functioning. It absolutely must be fixed. Users can't suddenly see their build broken if their directory name has a non-ASCII character in it.
