Question

我正在开发一个AEM项目，并在构建我的maven项目时遇到以下错误。

Failed to execute goal org.apache.felix:maven-scr-plugin:1.20.0:scr (generate-scr-scrdescriptor) on project acs.core: Execution generate-scr-scrdescriptor of goal org.apache.felix:maven-scr-plugin:1.20.0:scr failed: **Could not load the propery file 'output_xml.properties' for output method 'xml' (check CLASSPATH)** -> [Help 1]

不确定它引用“output_xml.properties”文件的位置。

Answer 1

org.apache.felix：maven-scr-plugin插件，使用这个插件，它必须在项目描述符中声明为元素：

<project>
...
<build>
...
<plugins>
  ...
  <plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-scr-plugin</artifactId>
    <version>1.20.0</version>
    <executions>
      <execution>
        <id>generate-scr-scrdescriptor</id>
        <goals>
          <goal>scr</goal>
        </goals>
      </execution>
    </executions>
  </plugin>
  ...
</plugins>
...
</build>
...
</project>

如果您想使用maven-scr-plugin处理标准注释，请添加此依赖项：

<project>
...
<dependencies>
...
<dependency>
     <groupId>org.apache.felix</groupId>
     <artifactId>org.apache.felix.scr.ds-annotations</artifactId>
     <version>1.2.4</version>
     <scope>provided</scope>
</dependency>
...
</dependencies>
...
</project>

几个月的迟到答案，但我能够通过导入和使用SlingAllMethodsServlet扩展我的类来解决我的错误

...
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
...

public class Something extends SlingAllMethodsServlet ....{
    ...
}

无法执行目标org.apache.felix：maven-scr-plugin：1.20.0
