问题描述

如何在普通的maven项目和maven插件项目中访问pom中定义的maven属性？

How do I access maven properties defined in the pom in a normal maven project, and in a maven plugin project?

推荐答案

使用 properties-maven-plugin 写出特定的pom 属性在编译时放入文件，然后在运行时读取该文件。

Use the properties-maven-plugin to write out specific pom properties into a file at compile time, and then read that file at run time.

在 pom.xml ：

<properties>
     <name>${project.name></name>
     <version>${project.version}</version>
     <foo>bar</foo>
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>properties-maven-plugin</artifactId>
            <version>1.0.0</version>
            <executions>
                <execution>
                    <phase>generate-resources</phase>
                    <goals>
                        <goal>write-project-properties</goal>
                    </goals>
                    <configuration>
                        <outputFile>${project.build.outputDirectory}/my.properties</outputFile>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

然后在 .java ：

java.io.InputStream is = this.getClass().getResourceAsStream("my.properties");
java.util.Properties p = new Properties();
p.load(is);
String name = p.getProperty("name");
String version = p.getProperty("version");
String foo = p.getProperty("foo");
