Hi Chris, I was trying one workflow of creating / running an Edgent app - in this case trying to use mvn exec:java I’m lead to believe there’s some problem with poms/deps. This was using PR-309 content from this am.
The app itself doesn’t use slf4j. Edgent has a compile time dependency on slf4j-api. At runtime, a single slf4j impl must be present. The failure below seems to indicate that slf4j-api isn’t present (that seems to be where org.slf4j.LoggerFactory is)? Related to the top level pom specifying “provided” for slf4j-api? Here’s the flow… Lacking an Edgent specific archetype template, I faked it: mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false then added these deps to its pom: <dependency> <groupId>org.apache.edgent.providers</groupId> <artifactId>edgent-providers-direct</artifactId> <version>1.2.0-SNAPSHOT</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-jdk14</artifactId> <version>1.7.12</version> <scope>runtime</scope> </dependency> then I essentially copied the HelloEdgent.java sample into the generated App.java (tweaking package&classname) then mvn clean package -DskipTests mvn exec:java -Dexec.mainClass=“com.mycompany.app.App” java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory at org.apache.edgent.runtime.jsoncontrol.JsonControlService.<clinit>(JsonControlService.java:50) at org.apache.edgent.providers.direct.DirectProvider.<init>(DirectProvider.java:60) at com.mycompany.app.App.main(App.java:20) ...
