The idea for this article on resolving a Maven-scr-Plugin Error in AEM came about while building an AEM project using the Maven command. When we encountered this problem, we decided to explain the cause and the way to solve this error.<\/div>\n

mvn clean install -P <Profile Name><\/pre>\n<\/div>\n
The Maven-scr-plugin error description is as shown below<\/b><\/h6>\n
\n
[ERROR] Failed to execute goal org.apache.felix:maven-scr-plugin:1.7.4:scr (generate-scr-descriptor) on project blog-bundle: SCR Descriptor parsing had failures (see log) -> [Help 1]\r\n[ERROR]\u00a0\r\n[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.\r\n[ERROR] Re-run Maven using the -X switch to enable full debug logging.\r\n[ERROR]\u00a0\r\n[ERROR] For more information about the errors and possible solutions, please read the following articles:\r\n[ERROR] [Help 1] http:\/\/cwiki.apache.org\/confluence\/display\/MAVEN\/MojoFailureException\r\n[ERROR]\u00a0\r\n[ERROR] After correcting the problems, you can resume the build with the command\r\n\r\n\r\n[ERROR] \u00a0 mvn <goals> -rf :blog-bundle<\/pre>\n
 <\/p>\n<\/div>\n
Cause of Maven-scr-Plugin error<\/b><\/h6>\n
Most of the time this Maven-scr-pugin error occurs when you use the following two annotations together –<\/div>\n
@SlingServlet<\/i> and @Component\u00a0<\/i>same class.<\/div>\n
\n
<\/div>\n
For Example, if your coding syntax is<\/div>\n
<\/div>\n
\n
@SlingServlet(path=\"\/bin\/blog\" extension=\"html\")\r\n@Component\r\nClass TestServlet extends SlingSafeMethodsServlet { \/* \u00a0----------------------- *\/\u00a0}<\/pre>\n
 <\/p>\n
In this case you will get that error,\u00a0<\/i>because\u00a0@SlingServlet <\/i>has “generateComponent”<\/i> property and by default its value is “true”<\/em>\u00a0so ideally you don’t provide the\u00a0@Component<\/i>\u00a0annotation.<\/p>\n<\/div>\n<\/div>\n
How to resolve this Maven issue<\/b><\/h6>\n
There are two ways to resolve this issue –<\/div>\n
    \n
  1. Remove\u00a0@Component<\/b>\u00a0annotation while creating Sling Servlet.<\/li>\n
  2. The issues with the first solution are –\n
      \n
    1. Unable to activate this Sling Servlet immediately: <\/strong>The timing of activation of this Sling Servlet\u00a0is totally dependent on Felix <\/b>implementation. This means it may or may not be in active state after deploying the package.<\/li>\n
    2. We are not able to use\u00a0immediate, enabled metatype<\/b> and other properties provided by @Component.<\/b><\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

      \n<\/i>The preferred way to use these annotations is<\/b><\/h6>\n
      \n
      @SlingServlet(path=\"\/bin\/blog\" extension=\"html\",\u00a0generateComponent=false)\r\n@Component\r\nClass TestServlet extends SlingSafeMethodsServlet {\u00a0\/* \u00a0----------------------- *\/\u00a0}<\/pre>\n<\/div>\n
