与Ant相比，Buildr遵循“约定优于配置”原则，使“编译、测试、打包”更容易。
与Maven相比，开发者无需理解强大且复杂的模型，而采用Ruby/Rake作为脚本的基础，也使得开发者可以定制属于自己的脚本。
特性：
1、可以读取Maven的pom.xml构建文件，创建Buildr的构建文件
2、支持ANTLR解析器
3、支持Hibernate XDoclet和Schema任务
4、支持JUnit/TestNG测试框架
5、支持所有Ant的任务，只要你会用ant，你就会用buildr
Apache Buildr 1.4.22 发布，此版本更新内容如下：
* Change: BUILDR-704 - Updated the Sonar addon to support the latest version of SonarQube Runner. Submitted by Ross Mahony. * Added: Add support for ipr.add_glassfish_remote_configuration method that generates a remote glassfish configuration in IntelliJ IDEA project files. * Added: Add support for iml.prefix and ipr.prefix settings that prefix the generated IntelliJ IDEA project and module files. * Change: Update the buildr gemspec so that rspec is no longer a required dependency. This enables end-users to use a different version of rspec and buildr in the same project. The rspec version MUST be be compatible with the version used by Buildr if rspec features are used from within Buildr. Buildr also issues a warning if the `check` method is called and rspec has not been loaded. The warning includes directions on how to resolve the issue. Submitted by r6p. * Fixed: A long standing bug existed such that if tests failed to compile, and the option Buildr.options.test is set to :all then the compilation error would not result in a failed build. As many people set the Buildr.options.test to :all in their continuous delivery/integration tools, this has caused some problems. This has been fixed by ensuring all the problems associated with the resolving the prerequisites are not caught when Buildr.options.test is set to :all. * Change: Update checkstyle to 6.1.1. Submitted by neher. * Fixed: Avoid empty dependency issue in gwt addon if the attempting to gwt compile a project that has no src/main/java. * Fixed: Support dependencies in the gwt addon that are other local projects rather that artifacts, without forcing a compilation of dependency when parsing buildfile. * Added: Support configuration of sql dialect mapping in IDEA generated project files through methods on the ipr extension ipr.mssql_dialect_mapping, ipr.postgres_dialect_mapping and ipr.sql_dialect_mappings * Added: Support specification of the target project to which the gwt compilation artifacts are added as an asset, by using :target_project option.Thanks!
