I am trying to build darknet_ros custom messages, but it always fail.
Checking subfolder "darknet_ros_msgs" for custom messages.
Building custom message files for the following packages:
darknet_ros_msgs
:rosjava_messages is spawning subprojects: [darknet_ros_msgs]
Creating properties on demand (a.k.a. dynamic properties) has been deprecated and is scheduled to be removed in Gradle 2.0. Please read http://gradle.org/docs/current/dsl/org.gradle.api.plugins.ExtraPropertiesExtension.html for information on the replacement for dynamic properties.
Deprecated dynamic property: "mavenRepository" on "org.ros.gradle_plugins.RosPluginExtension_Decorated@329312cd", value: "".

Total time: 4.294 secs
An error occurred while building custom messages. See the full error message above.
Possible reasons for the error:
1. The msg or srv files may have syntax errors.
2. The dependencies on other message packages may not be declared correctly in the build_depends tags in the package.xml.
3. Messages packages declared as dependencies may not be available.
4. The custom message packages may be missing a build dependency on "message_generation".
See the ROS Custom Messages documentation for more information.
