Now, MyBoundQueryMojo default phase which is package has been overridden by install phase. How about if we have a multiple executions with different phases bound to it? How do you think will it behave? Let us use the example POM above again, but this time we shall bind execution2 to a phase. The same applies to executions that are defined by profiles. Executions of the same id from different POMs are merged. Note that while execution id's have to be unique among all executions of a single plugin within a POM, they don't have to be unique across an inheritance hierarchy of POMs. But if the goal is not bound to any lifecycle phase then it simply won't be executed during the build lifecycle. If the goal has a default phase binding then it will execute in that phase. The second execution does not have a tag, how do you think will this execution behave? Well, goals can have a default phase binding as discussed further below. The first execution with id 'execution1' binds this configuration to the test phase.

This approach is also used if configuring collection/array parameters via command line The following example is equivalent to the example above:

Since Maven 3.3.9 ( MNG-5440), you can list individual items alternatively as comma-separated list in the XML value of animals directly. If the element has no children, assume its type is String.Use the parameter type information from either Field.getGenericType() or Method.getGenericParameterTypes().Try the XML element name (with capitalized first letter) as a class in the same package as the mojo/object being configured., try to load the class with the fully qualified class name given in the element name If the XML element contains an implementation hint attribute, try to load the class with the given fully qualified class name from the attribute value.In order to derive the type of a collection item, the following strategy is used: Unlike arrays, collections do not necessarily have a specific component type. Where each of the animals listed would be entries in the animals field. The element might look like the following: Let's look at a simple example where we are trying to map a configuration for Person object. Mapping complex types is also fairly straight forward. In case the file is relative, is is made absolute by prefixing it with the project's base directory. New File(String) with the file separators normalized to paratorChar.

SimpleDateFormat.parse(String) for the following patterns: yyyy-MM-dd hh:mm:ss.S a, yyyy-MM-dd hh:mm:ssa, yyyy-MM-dd HH:mm:ss.S or yyyy-MM-dd HH:mm:ss Parameter ClassĬharacter.valueOf(char) of the first character in the given string For conversion to primitive types their according wrapper classes are used and automatically unboxed. The detailed type coercion is explained in the table below. In the Mojo above, the parameter url is associated with the expression $, meaning its value can be specified by the system property query.url as shown below: The plugin documentation for those parameters will list an expression that denotes the system properties for the configuration. The mapping mechanism can deal with arrays by inspecting the type of the field and determining if a suitable mapping is possible.įor Mojos that are intended to be executed directly from the CLI, their parameters usually provide a means to be configured via system properties instead of a section in the POM. The url element maps to the url field, the timeout element maps to the timeout field, and the options element maps to the options field. The elements in the configuration match the names of the fields in the Mojo. (Remember that a plug-in consists of one or more Mojos where a Mojo maps to a goal.) Say, for example, you have a Mojo that performs a query against a particular URL, with a specified timeout and list of options. Maven plugins (build and reporting) are configured by specifying a element where the child elements of the element are mapped to fields, or setters, inside your Mojo. For reporting plugins, specify each version in the element (and in the element too). Often the element is found in the parent POM. A good practice is to specify each build plugin's version in a element. Important Note: Always define the version of each plugin used to guarantee build reproducibility.

Reporting plugins are executed during the site generation and configured in the element.Īll plugins should have minimal required information: groupId, artifactId and version.

Build plugins are executed during the build and configured in the element.

In Maven, there are two kinds of plugins, build and reporting:
