[SNMP4J] cannot find symbol Re: agenpro-mvn-task log4j error

[Frank Fock]

Hi,

I am not sure what could be causing the specific error you
are getting below, but an important detail to keep in mind
is the following:

In the agenpro-mvn-task\pom.xml the order of dependencies
has to be changed, if you use newer versions of SNMP4J
or SNMP4J-Agent than those that came with your AgenPro
release. Thus, in general it is better to change the order
as follows:

<dependencies>
<dependency>
<groupId>org.snmp4j</groupId>
<artifactId>snmp4j</artifactId>
<version>2.0.3</version>
</dependency>
<dependency>
<groupId>org.snmp4j</groupId>
<artifactId>snmp4j-agent</artifactId>
<version>2.0.5</version>
</dependency>
<dependency>
<groupId>com.oosnmp.agenpro.maven.plugins</groupId>
<artifactId>agenpro-plugin</artifactId>
<version>3.1.2</version>
<scope>provided</scope>
</dependency>
</dependencies>

I will update the pom.xml for the next plugin release (coming up soon).

Best regards,
Frank
