             Summary: critical error with non-ASCII charcters in directory name: cannot read Input length = 1
                 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


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, core bug. It absolutely must be fixed. Users can't suddenly see their build broken if their directory name has a non-ASCII character in it.
