Summary: Fix incorrect output path in javadoc build phase Key: HADOOP-18751 URL: https://issues.apache.org/jira/browse/HADOOP-18751 Project: Hadoop Common Issue Type: Bug Components: build Affects Versions: 3.4.0 Environment: All Reporter: Gautham Banasandra Assignee: Gautham Banasandra The javadoc build phase fails with the following error - {code} [ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:3.0.1:javadoc-no-fork (default-cli) on project hadoop-common: An error has occurred in Javadoc report generation: Unable to write 'options' temporary file for command execution: H:\hadoop-common-project\hadoop-common\target\site\H:\hadoop-common-project\hadoop-common\target\api\options (The filename, directory name, or volume label syntax is incorrect) -> [Help 1] {code} As called out by the error message the path *H:\hadoop-common-project\hadoop-common\target\site\H:\hadoop-common-project\hadoop-common\target\api\options* is invalid. The culprit being - https://github.com/apache/hadoop/blob/e9740cb17aef157a615dc36ae08cd224ce1672f0/hadoop-project-dist/pom.xml#L109 {code} <reportOutputDirectory>${project.build.directory}/site</reportOutputDirectory> <destDir>${project.build.directory}/api</destDir> {code} As per the [docs from maven-javadoc-plugin|https://maven.apache.org/plugins/maven-javadoc-plugin/examples/output-configuration.html], *destDir* attribute's value gets appended to that of *reportOutputDirectory*. This implies that *destDir* must be a relative path, although not called out in the documentation. Since this isn't the case here, 1. In Linux, this yields an unintended path (albeit a valid one) and doesn't fail. 2. In Windows, it yields an incorrect path and thus fails since there's a colon (:) for the drive letter in the middle - H:\hadoop-common-project\hadoop-common\target\site\H*:*\hadoop-common-project\hadoop-common\target\api\options Thus, fixing this would fix the build failure on Windows and put the docs in the appropriate directory in Linux. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
