Appendix D. Fabric8 Camel Maven Plug-In
D.1. Goals
For validating Camel endpoints in the source code:
-
fabric8-camel:validatevalidates the Maven project source code to identify invalid camel endpoint uris
D.2. Adding the plugin to your project
To enable the Plugin, add the following to the pom.xml file:
<plugin> <groupId>io.fabric8.forge</groupId> <artifactId>fabric8-camel-maven-plugin</artifactId> <version>2.3.90</version> </plugin>
Note: Check the current version number of the fabric8-forge release. You can find the latest release at the following location: https://github.com/fabric8io/fabric8-forge/releases.
However, you can run the validate goal from the command line or from your Java editor such as IDEA or Eclipse.
mvn fabric8-camel:validate
You can also enable the Plugin to run automatically as a part of the build to catch the errors.
<plugin>
<groupId>io.fabric8.forge</groupId>
<artifactId>fabric8-camel-maven-plugin</artifactId>
<version>2.3.80</version>
<executions>
<execution>
<phase>process-classes</phase>
<goals>
<goal>validate</goal>
</goals>
</execution>
</executions>
</plugin>
The phase determines when the Plugin runs. In the above example, the phase is process-classes which runs after the compilation of the main source code.
You can also configure the maven plugin to validate the test source code. Change the phase as per the process-test-classes as shown below:
<plugin>
<groupId>io.fabric8.forge</groupId>
<artifactId>fabric8-camel-maven-plugin</artifactId>
<version>2.3.80</version>
<executions>
<execution>
<configuration>
<includeTest>true</includeTest>
</configuration>
<phase>process-test-classes</phase>
<goals>
<goal>validate</goal>
</goals>
</execution>
</executions>
</plugin>D.3. Running the Goal on any Maven Project
You can also run the validate goal on any Maven project, without adding the Plugin to the pom.xml file. You need to specify the Plugin, using its fully qualified name. For example, to run the goal on the camel-example-cdi plugin from Apache Camel, execute the following:
$cd camel-example-cdi
$mvn io.fabric8.forge:fabric8-camel-maven-plugin:2.3.80:validatewhich then runs and displays the following output:
[INFO] ------------------------------------------------------------------------ [INFO] Building Camel :: Example :: CDI 2.16.2 [INFO] ------------------------------------------------------------------------ [INFO] [INFO] --- fabric8-camel-maven-plugin:2.3.80:validate (default-cli) @ camel-example-cdi --- [INFO] Endpoint validation success: (4 = passed, 0 = invalid, 0 = incapable, 0 = unknown components) [INFO] Simple validation success: (0 = passed, 0 = invalid) [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------
After passing the validation successfully, you can validate the four endpoints. Let us assume that you made a typo in one of the Camel endpoint uris in the source code, such as:
@Uri("timer:foo?period=5000")
You can make changes to include a typo error in the period option, such as:
@Uri("timer:foo?perid=5000")And when running the validate goal again, reports the following:
[INFO] ------------------------------------------------------------------------ [INFO] Building Camel :: Example :: CDI 2.16.2 [INFO] ------------------------------------------------------------------------ [INFO] [INFO] --- fabric8-camel-maven-plugin:2.3.80:validate (default-cli) @ camel-example-cdi --- [WARNING] Endpoint validation error at: org.apache.camel.example.cdi.MyRoutes(MyRoutes.java:32) timer:foo?perid=5000 perid Unknown option. Did you mean: [period] [WARNING] Endpoint validation error: (3 = passed, 1 = invalid, 0 = incapable, 0 = unknown components) [INFO] Simple validation success: (0 = passed, 0 = invalid) [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------
D.4. Options
The maven plugin supports the following options which you can configure from the command line (use -D syntax), or defined in the pom.xml file in the <configuration> tag.
D.4.1. Table
| Parameter | Default Value | Description |
|---|---|---|
| downloadVersion | true | Whether to allow downloading Camel catalog version from the internet. This is needed, if the project uses a different Camel version than this plugin is using by default. |
| failOnError | false |
Whether to fail if invalid Camel endpoints was found. By default the plugin logs the errors at |
| logUnparseable | false | Whether to log endpoint URIs which was un-parsable and therefore not possible to validate |
| includeJava | true | Whether to include Java files to be validated for invalid Camel endpoints |
| includeXML | true | Whether to include XML files to be validated for invalid Camel endpoints |
| includeTest | false | Whether to include test source code |
| includes | - | To filter the names of java and xml files to only include files matching any of the given list of patterns (wildcard and regular expression). Multiple values can be separated by comma. |
| excludes | - | To filter the names of java and xml files to exclude files matching any of the given list of patterns (wildcard and regular expression). Multiple values can be separated by comma. |
| ignoreUnknownComponent | true | Whether to ignore unknown components |
| ignoreIncapable | true | Whether to ignore incapable of parsing the endpoint uri |
| ignoreLenientProperties | true | Whether to ignore components that uses lenient properties. When this is true, then the uri validation is stricter but would fail on properties that are not part of the component but in the uri because of using lenient properties. For example using the HTTP components to provide query parameters in the endpoint uri. |
| showAll | false | Whether to show all endpoints and simple expressions (both invalid and valid). |
D.5. Validating include test
If you have a Maven project, then you can run the plugin to validate the endpoints in the unit test source code as well. You can pass in the options using -D style as shown:
$cd myproject
$mvn io.fabric8.forge:fabric8-camel-maven-plugin:2.3.80:validate -DincludeTest=true
