Update the Shade Plugin version

[feinstein]

Right now the Maven shade plugin version is at 3.1.0 and your library's compatibility is at 2.4.3.
Please update the library to the latest Maven shade plugin version.

I get

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:3.1.0:shade (default) 
on project syi-platform: Unable to parse configuration of mojo org.apache.maven.plugins:maven-shade-plugin:3.1.0:shade for parameter resource: Cannot find 'resource' in class 
com.github.edwgiz.mavenShadePlugin.log4j2CacheTransformer.PluginsCacheFileTransformer -> [Help 1]

Using whatever version of shade. Not sure if it is related. Any ideas?

[PyvesB]

@paulosuzart what does you pom.xml look like?

[mrosner17]

@PyvesB I think I am seeing the same issue as paulosuzart.

[ncremaschini]

updates about this?

[mrosner17]

I got around it by using SLF4J. Still have bugs, but at least I am getting something to log to Cloudwatch.

[nmichalares]

May not be the right spot for this, but I was led here with the same error as what's mentioned above:

I am seeing this error pop up when I bring in spring boot parent.

[Ghilteras]

Got into this as well, looks like I cannot use aws-lambda-java-libs with shade

[MarkusKramer]

For me, the issue was caused by having a parent pom. Removing the parent solved it for me.

[NicholasPurdy]

@ncremaschini I too am trying to get the custom AWS lambda appender to work with Spring Boot. For now, I am using a Logback configuration that can log stack traces as a single CloudWatch event. You can find it on my GitHub page.

[vdsysvd]

I solved the same issue adding the id tag inside the execution section
<executions> <execution> <id>shade-jar</id> <phase>package</phase> <goals> <goal>shade</goal>....

[kkishoreathena]

@vdsysvd could you throw some light on why this worked?
