For example, many commands take 31a project list as an argument. You can specify project-list as a list of names 32or a list of paths to local source directories for the projects:</p> 33<pre><code>repo sync [<em><PROJECT0></em> <em><PROJECT1></em> <em><PROJECTN></em>] 34repo sync [<em></PATH/TO/PROJECT0></em> ... <em></PATH/TO/PROJECTN></em>] 35</code></pre> 36 37<h2 id="help">help</h2> 38<p>Once Repo is installed, you can find the latest documentation starting with a summary of all commands by running:</p> 39<pre><code>repo help 40</code></pre> 41<p>You can get information about any command by running this within a Repo tree:</p> 42<pre><code>repo help <em><COMMAND></em> 43</code></pre> 44 45<h2 id="init">init</h2> 46<pre><code>$ repo init -u <em><URL></em> [<em><OPTIONS></em>] 47</code></pre> 48<p>Installs Repo in the current directory. This creates a <code>.repo/</code> directory that contains Git repositories for the Repo source code and the standard Android manifest files. The <code>.repo/</code> directory also contains <code>manifest.xml</code>, which is a symlink to the selected manifest in the <code>.repo/manifests/</code> directory.</p> 49<p>Options:</p> 50<ul> 51<li> 52<p><code>-u</code>: specify a URL from which to retrieve a manifest repository. The common manifest can be found at <code>https://android.googlesource.com/platform/manifest</code></p> 53</li> 54<li> 55<p><code>-m</code>: select a manifest file within the repository. If no manifest name is selected, the default is default.xml. </p> 56</li> 57<li> 58<p><code>-b</code>: specify a revision, i.e., a particular manifest-branch.</p> 59</li> 60</ul> 61<p><em>Note: For all remaining Repo commands, the current working directory must either be the parent directory of <code>.repo/</code> or a subdirectory of the parent directory.</em></p> 62<h2 id="sync">sync</h2> 63<pre><code>repo sync [<em><PROJECT_LIST></em>] 64</code></pre> 65<p>Downloads new changes and updates the working files in your local environment. If you run <code>repo sync</code> without any arguments, it will synchronize the files for all the projects.</p> 66<p>When you run <code>repo sync</code>, this is what happens:</p> 67<ul> 68<li> 69<p>If the project has never been synchronized, then <code>repo sync</code> is equivalent to <code>git clone</code>. All branches in the remote repository are copied to the local project directory.</p> 70</li> 71<li> 72<p>If the project has already been synchronized once, then <code>repo sync</code> is equivalent to:</p> 73<pre><code>git remote update 74git rebase origin/<em><BRANCH></em> 75</code></pre> 76<p>where <code><em><BRANCH></em></code> is the currently checked-out branch in the local project directory. If the local branch is not tracking a branch in the remote repository, then no synchronization will occur for the project.</p> 77</li> 78<li> 79<p>If the git rebase operation results in merge conflicts, you will need to use the normal Git commands (for example, <code>git rebase --continue</code>) to resolve the conflicts.</p> 80</li> 81</ul> 82<p>After a successful <code>repo sync</code>, the code in specified projects will be up to date with the code in the remote repository.</p> 83<p>Options:</p> 84<ul> 85<li> 86<p><code>-d</code>: switch specified projects back to the manifest revision. Helpful if the project is currently on a topic branch, but the manifest revision is temporarily needed.</p> 87</li> 88<li> 89<p><code>-s</code>: sync to a known good build as specified by the manifest-server element in the current manifest.</p> 90</li> 91<li> 92<p><code>-f</code>: proceed with syncing other projects even if a project fails to sync.</p> 93</li> 94</ul> 95<h2 id="upload">upload</h2> 96<pre><code>repo upload [<em><PROJECT_LIST></em>] 97</code></pre> 98<p>For the specified projects, Repo compares the local branches to the remote branches updated during the last repo sync. Repo will prompt you to select one or more of the branches that have not yet been uploaded for review.</p> 99<p>After you select one or more branches, all commits on the selected branches 100are transmitted to Gerrit over an HTTPS connection. You will need to 101configure an HTTPS password to enable upload authorization. Visit the 102<a href="https://android-review.googlesource.com/new-password">Password Generator</a> 103to generate a new username/password pair to use over HTTPS.</p> 104<p>When Gerrit receives the object data over its server, it will turn each 105commit into a change so that reviewers can comment on each commit 106individually. To combine several "checkpoint" commits together into a 107single commit, use git rebase -i before you run repo upload.</p> 108<p>If you run repo upload without any arguments, it will search all the projects for changes to upload.</p> 109<p>To make edits to changes after they have been uploaded, you should use a tool like <code>git rebase -i</code> or <code>git commit --amend</code> to update your local commits. After your edits are complete:</p> 110<ul> 111<li> 112<p>Make sure the updated branch is the currently checked out branch.</p> 113</li> 114<li> 115<p>For each commit in the series, enter the Gerrit change ID inside the brackets:</p> 116<pre><code># Replacing from branch foo 117[ 3021 ] 35f2596c Refactor part of GetUploadableBranches to lookup one specific... 118[ 2829 ] ec18b4ba Update proto client to support patch set replacments 119# Insert change numbers in the brackets to add a new patch set. 120# To create a new change record, leave the brackets empty. 121</code></pre> 122</li> 123</ul> 124<p>After the upload is complete the changes will have an additional Patch Set.</p> 125<h2 id="diff">diff</h2> 126<pre><code>repo diff [<em><PROJECT_LIST></em>] 127</code></pre> 128<p>Shows outstanding changes between commit and working tree using <code>git diff</code>. </p> 129<h2 id="download">download</h2> 130<pre><code>repo download <em><TARGET></em> <em><CHANGE></em> 131</code></pre> 132<p>Downloads the specified change from the review system and makes it available in your project's local working directory.</p> 133<p>For example, to download <a href="https://android-review.googlesource.com/23823">change 23823</a> into your platform/frameworks/base directory:</p> 134<pre><code>$ repo download platform/build 23823 135</code></pre> 136<p>A <code>repo sync</code> should effectively remove any commits retrieved via <code>repo download</code>. Or, you can check out the remote branch; e.g., <code>git checkout m/master</code>.</p> 137<p>*Note: There is a slight mirroring lag between when a change is visible on 138the web in <a href="https://android-review.googlesource.com/">Gerrit</a> and when 139<code>repo download</code> will be able to find it for all users, because of replication 140delays to all servers worldwide.</p> 141<h2 id="forall">forall</h2> 142<pre><code>repo forall [<em><PROJECT_LIST></em>] -c <em><COMMAND></em> 143</code></pre> 144<p>Executes the given shell command in each project.
