You can also install Maven (>=3.3.3) yourself and run the <code>mvn</code> command
in place of <code>./mvnw</code> in the examples below. If you do that you also
might need to add <code>-P spring</code> if your local Maven settings do not
contain repository declarations for spring pre-release artifacts.

Be aware that you might need to increase the amount of memory
available to Maven by setting a <code>MAVEN_OPTS</code> environment variable with
a value like <code>-Xmx512m -XX:MaxPermSize=128m</code>. We try to cover this in
the <code>.mvn</code> configuration, so if you find you have to do it to make a
build succeed, please raise a ticket to get the settings added to
source control.

<div class="paragraph">
<p>For hints on how to build the project look in <code>.travis.yml</code> if there
is one. There should be a "script" and maybe "install" command. Also
look at the "services" section to see if any services need to be
running locally (e.g. mongo or rabbit). Ignore the git-related bits
that you might find in "before_install" since they’re related to setting git
credentials and you already have those.</p>
</div>

<p>The projects that require middleware generally include a
<code>docker-compose.yml</code>, so consider using
<a href="https://docs.docker.com/compose/">Docker Compose</a> to run the middeware servers
in Docker containers. See the README in the
<a href="https://github.com/spring-cloud-samples/scripts">scripts demo

<p>The spring-cloud-build module has a "docs" profile, and if you switch
that on it will try to build asciidoc sources from
<code>src/main/asciidoc</code>. As part of that process it will look for a
<code>README.adoc</code> and process it by loading all the includes, but not
parsing or rendering it, just copying it to <code>${main.basedir}</code>
(defaults to <code>${basedir}</code>, i.e. the root of the project). If there are
any changes in the README it will then show up after a Maven build as
a modified file in the correct place. Just commit it and push the change.</p>

<a href="https://eclipse.org">Eclipse</a> when working with the code. We use the
<a href="https://eclipse.org/m2e/">m2eclipse</a> eclipse plugin for maven support. Other IDEs and tools

Older versions of m2e do not support Maven 3.3, so once the
projects are imported into Eclipse you will also need to tell
m2eclipse to use the right profile for the projects. If you
see many different errors related to the POMs in the projects, check
that you have an up to date installation. If you can’t upgrade m2e,
add the "spring" profile to your <code>settings.xml</code>. Alternatively you can
copy the repository settings from the "spring" profile of the parent

<p>Use the Spring Framework code format conventions. If you use Eclipse

</li>
<li>
<p>Make sure all new <code>.java</code> files to have a simple Javadoc class comment with at least an
<code>@author</code> tag identifying you, and preferably at least a paragraph on what the class is
for.</p>
</li>
<li>
<p>Add the ASF license header comment to all new <code>.java</code> files (copy from existing files
in the project)</p>
</li>
<li>
<p>Add yourself as an <code>@author</code> to the .java files that you modify substantially (more
than cosmetic changes).</p>
</li>
<li>
<p>Add some Javadocs and, if you change the namespace, some XSD doc elements.</p>

other target branch in the main project).</p>

<p>To have Intellij work with Checkstyle, you have to install the <code>Checkstyle</code> plugin. It’s advisable to also install the <code>Assertions2Assertj</code> to automatically convert the JUnit assertions</p>

<div class="paragraph">
<p>Go to <code>File</code> → <code>Settings</code> → <code>Other settings</code> → <code>Checkstyle</code>. There click on the <code>+</code> icon in the <code>Configuration file</code> section. There, you’ll have to define where the checkstyle rules should be picked from. In the image above, we’ve picked the rules from the cloned Spring Cloud Build repository. However, you can point to the Spring Cloud Build’s GitHub repository (e.g. for the <code>checkstyle.xml</code> : <code><a href="https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/main/resources/checkstyle.xml" class="bare">https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/main/resources/checkstyle.xml</a></code>). We need to provide the following variables:</p>
</div>
<div class="ulist">
<ul>
<li>
<p><code>checkstyle.header.file</code> - please point it to the Spring Cloud Build’s, <code>spring-cloud-build-tools/src/main/resources/checkstyle/checkstyle-header.txt</code> file either in your cloned repo or via the <code><a href="https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/main/resources/checkstyle-header.txt" class="bare">https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/main/resources/checkstyle-header.txt</a></code> URL.</p>
</li>
<li>
<p><code>checkstyle.suppressions.file</code> - default suppressions. Please point it to the Spring Cloud Build’s, <code>spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml</code> file either in your cloned repo or via the <code><a href="https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml" class="bare">https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml</a></code> URL.</p>
</li>
<li>
<p><code>checkstyle.additional.suppressions.file</code> - this variable corresponds to suppressions in your local project. E.g. you’re working on <code>spring-cloud-contract</code>. Then point to the <code>project-root/src/checkstyle/checkstyle-suppressions.xml</code> folder. Example for <code>spring-cloud-contract</code> would be: <code>/home/username/spring-cloud-contract/src/checkstyle/checkstyle-suppressions.xml</code>.</p>
</li>
</ul>
