Re: [ANNOUNCE] Apache Groovy 2.5.9 released

It appears that the online documentation is missing:

MissingMethodException

[Robert Stagner]

I'm thoroughly *stumped* by a recent MissingMethodException.  When I
execute the code on an Amazon EC2 instance, I consistently receive the
noted exception.

However, when I run the code on my local Linux workstation, the tests *pass
successfully*.  Here are the specs on the EC2 instance

Java:

java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)


Maven:

Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe;
2018-06-17T18:33:14Z)

OS name: "linux", version: "4.14.138-114.102.amzn2.x86_64", arch: "amd64",
family: "unix"



And, here is the error message Groovy is throwing. I've checked the code
and I am calling the method correctly.  From the message below, it would
seem to be a class loader issue.  Unfortunately, I have no experience with
resolving this sort of issue.  Any help would be appreciated.

Re: Availability of 2.5.0 groovy-all in Maven Central

[Robert Stagner]

Thanks, Daniel.  This certainly helps.

When you stated "I've refine doco" what are you referring to?  I'm assuming
the documentation.  I reviewed the documentation, specifically,
http://docs.groovy-lang.org/latest/html/documentation/#_maven_integration,
and I do not see a reference to the pom statement.  Am I
missing something here?

Re: Availability of 2.5.0 groovy-all in Maven Central

[Robert Stagner]

Daniel,

Like the others, I ran into a similar error

Failure to find org.codehaus.groovy:groovy-all:jar:2.5.0 in
https://repo.maven.apache.org/maven2 was cached in the local repository,
resolution will not be reattempted until the update interval of central has
elapsed or updates are forced -> [Help 1]

I am also using IntelliJ IDEA.  And, like you I receive the error from the
command line.  Once I include pom it worked.

Re: Availability of 2.5.0 groovy-all in Maven Central

[Robert Stagner]

Daniel,

How should this be addressed in the POM file, for those of us using Maven
to grab groovy-all?

I tried the simple coordinates like


org.codehaus.groovy
groovy-all
2.5.0


but that did not work for me.

Re: [ANNOUNCE] MirComp 1.0.0-alpha.1 Released

[Robert Stagner]

Fantastic work!! I've just installed it on my MacBook Pro and my Linux
laptop running Kubuntu 14.04 and it works fine on both instances.  Thanks
for this.  I plan on sharing this with my daughter (16) who plays the flute
for her high school band.
