Question

从何处获取在Maven中gmaven-plugin下执行的Groovy脚本中可用变量的完整列表？除此之外，也许有人知道在哪里可以找到Gmaven文档？

我知道project和settings。我假设还有其他一些......

Answer 1

页面http://docs.codehaus.org/display/GMAVEN/Executing+Groovy+Code列出：

Default Variables
By default a few variables are bound into the scripts environment:

project  The maven project, with auto-resolving properties
pom  Alias for project
session  The executing MavenSession
settings     The executing Settings
log  A SLF4J Logger instance
ant  An AntBuilder instance for easy access to Ant tasks
fail()   A helper to throw MojoExecutionException

Answer 2

pom中的这个片段可以让您更好地了解运行脚本时可用的内容。大多数有趣的位可能都在binding.project中，是MavenProject的一个实例。

    <build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.groovy.maven</groupId>
            <artifactId>gmaven-plugin</artifactId>
            <executions>
                <execution>
                    <phase>generate-resources</phase>
                    <goals>
                        <goal>execute</goal>
                    </goals>
                    <configuration>
                        <properties>
                            <hello>world</hello>
                        </properties>
                        <source>
                            println this.binding.variables
                            println project.properties
                            println settings.properties
                        </source>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

哪里可以获得gmaven-plugin中预定义变量的完整列表？
