Analyzer\nSebastian Daschner\n\nThe JAX-RS Analyzer generates an overview of all JAX-RS resources in a JavaEE project.\nBesides other approaches this tool uses Bytecode analysis to maximise the extracted information.\n\nThe Analyzer is available as https://github.com/sdaschner/jaxrs-analyzer-maven-plugin/[Maven plugin] or standalone version (executable jar file).\n\n== Quickstart (tl;dr)\nJust add the latest release version of the JAX-RS Analyzer to your Maven pom.xml in the ``-section:\n\n----\n\n com.sebastian-daschner\n jaxrs-analyzer-maven-plugin\n 0.17\n \n \n \n analyze-jaxrs\n \n \n swagger\n \n \n \n\n----\n\nFor an introductional video see https://blog.sebastian-daschner.com/entries/jaxrs_analyzer_explained_video[JAX-RS Analyzer explained (Video)].\n\n== Maven Plugin\nPlease see the https://github.com/sdaschner/jaxrs-analyzer-maven-plugin[Maven plugin project] and a https://github.com/sdaschner/jaxrs-analyzer-maven-plugin/blob/master/Documentation.adoc[documentation] of all parameters.\n\n== Standalone\nInstead of using the Maven plugin, the tool can also run directly from the jar file.\n\nYou can download the latest version https://github.com/sdaschner/jaxrs-analyzer/releases[here].\nAlternatively the executable can be build with `mvn clean install`.\n\nRun the jar file with `java -jar jaxrs-analyzer.jar [options] [projectPathToCompiledClasses...]`, e.g. `java -jar jaxrs-analyzer.jar -b swagger ../yourProject/target/classes`.\n\nThe `projectPath` entries may be directories or jar files containing the classes to be analyzed.\n\nFollowing available options:\n\n* `-b ` The backend to choose: `swagger` (default), `plaintext`, `asciidoc`, `markdown`\n* `-cp [:class paths...]` The additional class paths containing classes which are used in the project (separated by colon); this may be directories or jar-files\n* `-X` Debug enabled (prints error debugging information on Standard error out)\n* `-n ` The name of the project\n* `-v ` The version of the project\n* `-d ` The domain of the project\n* `-o ` The location of the analysis output (will be printed to standard out if omitted)\n\nFollowing available backend specific options (only have effect if the corresponding backend is selected):\n\n* `--swaggerSchemes [,schemes]` The Swagger schemes: `http` (default), `https`, `ws`, `wss`\n* `--renderSwaggerTags` Enables rendering of Swagger tags (default tag will be used per default)\n* `--swaggerTagsPathOffset ` The number at which path position the Swagger tags will be extracted (0 will be used per default)\n* `--ignoredRootResources ` JAX-RS root resource classes which should be ignored by analyze (empty per default). Note that these ignores only cause the classes to be ignored as root resources; they might still be taken into account as JAX-RS sub-resources.\n\n== Backends\nThe Analyzer supports Plaintext, AsciiDoc, Markdown and Swagger as output format.\nThe latter three can be processed further.\n\nAsciiDoc and Markdown are human-readable, lightweight markup languages.\nThey can easily converted to PDF, HTML, and many more.\n\nThe Swagger JSON file can be used with Swagger UI or the http://editor.swagger.io[Swagger Editor].\n\n Swagger UI is a dependency-free collection of HTML, Javascript, and CSS assets that dynamically generate beautiful documentation from a Swagger-compliant API.\n\n== Changelog\nFor the latest changes see the https://github.com/sdaschner/jaxrs-analyzer/blob/master/Changelog.adoc[Changelog].\n\n== Contributing\nFeedback, bug reports and ideas for improvement are very welcome!
