Your configuration
元素定义在一个内部execution
因此适用于此execution
only.
所以要么打电话mvn initialize
(或之后的一个阶段initialize
)使用configuration
您当前的execution
捆绑。
或者使用全局configuration
:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>properties-maven-plugin</artifactId>
<version>1.0-alpha-2</version>
<configuration>
<files>
<file>etc/config/dev.properties</file>
</files>
</configuration>
...
</plugin>
然后打电话
mvn properties:read-project-properties
但这在这个插件的特定情况下没有多大意义(您希望属性在构建期间可用),因此这给您留下了第一个解决方案。
Update:我自己做了一个测试,确实使用了以下 POM:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.stackoverflow</groupId>
<artifactId>Q2664362</artifactId>
<version>1.0-SNAPSHOT</version>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>properties-maven-plugin</artifactId>
<version>1.0-alpha-2</version>
<executions>
<execution>
<phase>initialize</phase>
<goals>
<goal>read-project-properties</goal>
</goals>
<configuration>
<files>
<file>etc/config/dev.properties</file>
</files>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>${junit.version}</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
Running mvn test
不起作用:maven 将尝试下载junit:jar:${junit.version}
(即它不使用属性的值)这显然会失败。
$ mvn test

奇怪的是,依赖项的下载发生在properties:read-project-properties
。我不确定,但这听起来像是一个错误,你应该打开an issue.
