A defined set of repositories comprises the workspace. Source files in repositories are organized in a nested hierarchy of packages, where each package is a directory that contains a set of related source files and one <code translate="no" dir="ltr">BUILD</code> file. The <code translate="no" dir="ltr">BUILD</code> file specifies what software outputs can be built from the source.</p> <h3 id="repositories" data-text="Repositories" tabindex="-1">Repositories</h3> <p>Source files used in a Bazel build are organized in <em>repositories</em> (often shortened to <em>repos</em>). A repo is a directory tree with a boundary marker file at its root; such a boundary marker file could be <code translate="no" dir="ltr">MODULE.bazel</code>, <code translate="no" dir="ltr">REPO.bazel</code>, or in legacy contexts, <code translate="no" dir="ltr">WORKSPACE</code> or <code translate="no" dir="ltr">WORKSPACE.bazel</code>.</p> <p>The repo in which the current Bazel command is being run is called the <em>main repo</em>. Other, (external) repos are defined by <em>repo rules</em>; see <a href="/external/overview">external dependencies overview</a> for more information.</p> <h2 id="workspace" data-text="Workspace" tabindex="-1">Workspace</h2> <p>A <em>workspace</em> is the environment shared by all Bazel commands run from the same main repo. It encompasses the main repo and the set of all defined external repos.</p> <p>Note that historically the concepts of "repository" and "workspace" have been conflated; the term "workspace" has often been used to refer to the main repository, and sometimes even used as a synonym of "repository".</p> <h2 id="packages" data-text="Packages" tabindex="-1">Packages</h2> <p>The primary unit of code organization in a repository is the <em>package</em>. A package is a collection of related files and a specification of how they can be used to produce output artifacts.</p> <p>A package is defined as a directory containing a <a href="/concepts/build-files"><code translate="no" dir="ltr">BUILD</code> file</a> named either <code translate="no" dir="ltr">BUILD</code> or <code translate="no" dir="ltr">BUILD.bazel</code>. A package includes all files in its directory, plus all subdirectories beneath it, except those which themselves contain a <code translate="no" dir="ltr">BUILD</code> file. From this definition, no file or directory may be a part of two different packages.</p> <p>For example, in the following directory tree there are two packages, <code translate="no" dir="ltr">my/app</code>, and the subpackage <code translate="no" dir="ltr">my/app/tests</code>. Note that <code translate="no" dir="ltr">my/app/data</code> is not a package, but a directory belonging to package <code translate="no" dir="ltr">my/app</code>.</p> <div></div><devsite-code><pre class="devsite-click-to-copy" translate="no" dir="ltr" is-upgraded syntax="Text only"><code translate="no" dir="ltr">src/my/app/BUILD src/my/app/app.cc src/my/app/data/input.txt src/my/app/tests/BUILD src/my/app/tests/test.cc </code></pre></devsite-code> <h2 id="targets" data-text="Targets" tabindex="-1">Targets</h2> <p>A package is a container of <em>targets</em>, which are defined in the package's <code translate="no" dir="ltr">BUILD</code> file. Most targets are one of two principal kinds, <em>files</em> and <em>rules</em>.</p> <p>Files are further divided into two kinds. <em>Source files</em> are usually written by the efforts of people, and checked in to the repository. <em>Generated files</em>, sometimes called derived files or output files, are not checked in, but are generated from source files.</p> <p>The second kind of target is declared with a <em>rule</em>. Each rule instance specifies the relationship between a set of input and a set of output files. The inputs to a rule may be source files, but they also may be the outputs of other rules.</p> <p>Whether the input to a rule is a source file or a generated file is in most cases immaterial; what matters is only the contents of that file. This fact makes it easy to replace a complex source file with a generated file produced by a rule, such as happens when the burden of manually maintaining a highly structured file becomes too tiresome, and someone writes a program to derive it. No change is required to the consumers of that file. Conversely, a generated file may easily be replaced by a source file with only local changes.</p> <p>The inputs to a rule may also include <em>other rules</em>. The precise meaning of such relationships is often quite complex and language- or rule-dependent, but intuitively it is simple: a C++ library rule A might have another C++ library rule B for an input. The effect of this dependency is that B's header files are available to A during compilation, B's symbols are available to A during linking, and B's runtime data is available to A during execution.</p> <p>An invariant of all rules is that the files generated by a rule always belong to the same package as the rule itself; it is not possible to generate files into another package. It is not uncommon for a rule's inputs to come from another package, though.</p> <p>Package groups are sets of packages whose purpose is to limit accessibility of certain rules. Package groups are defined by the <code translate="no" dir="ltr">package_group</code> function. They have three properties: the list of packages they contain, their name, and other package groups they include. The only allowed ways to refer to them are from the <code translate="no" dir="ltr">visibility</code> attribute of rules or from the <code translate="no" dir="ltr">default_visibility</code> attribute of the <code translate="no" dir="ltr">package</code> function; they do not generate or consume files. For more information, refer to the <a href="/reference/be/functions#package_group"><code translate="no" dir="ltr">package_group</code> documentation</a>.</p> <p><a class="button button-with-icon button-primary" href="/concepts/labels"> Labels<span class="material-icons icon-after" aria-hidden="true" translate="no">arrow_forward</span> </a></p> </div> <devsite-thumb-rating position="footer"> </devsite-thumb-rating> <devsite-feedback position="footer" project-name="Bazel" product-id="5052038" bucket="https-bazel-build" context="" version="t-devsite-webserver-20250325-r00-rc03.468100743126793331" data-label="Send Feedback Button" track-type="feedback" track-name="sendFeedbackLink" track-metadata-position="footer" class="nocontent" project-icon="https://www.gstatic.com/devrel-devsite/prod/vd31e3ed8994e05c7f2cd0cf68a402ca7902bb92b6ec0977d7ef2a1c699fae3f9/bazel/images/touchicon-180.png" > <button> Send feedback </button> </devsite-feedback> <div class="devsite-floating-action-buttons"> </div> </article> <devsite-content-footer class="nocontent"> <p>Except as otherwise noted, the content of this page is licensed under the <a href="https://creativecommons.org/licenses/by/4.0/">Creative Commons Attribution 4.0 License</a>, and code samples are licensed under the <a href="https://www.apache.org/licenses/LICENSE-2.0">Apache 2.0 License</a>.
