paolo di tommaso commented on GROOVY-8571:
------------------------------------------
I see, but why the above code would fail? The first time the x is declared but
*not* assigned. Therefore it should be fine to have `x = 'foo'` in the
following line.
> Variable [XXX] is declared final but is reassigned false positive error

> Key: GROOVY-8571
> URL: https://issues.apache.org/jira/browse/GROOVY-8571
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.5.0-rc-2
> Reporter: paolo di tommaso
> Priority: Major
>
> Groovy version 2.5.0-rc-2 may report false positive final variable
> reassignment compilation errors.
> For example:
> {code}
> MailerTest.groovy: -1: The variable [PORT] is declared final but is reassigned
> {code}
> The source code is available at [this
> link|https://github.com/nextflow-io/nextflow/blob/90f8dcc5d413af06a76e8f7b3e37c5616f721024/src/test/groovy/nextflow/mail/MailerTest.groovy#L120].

> To replicate the issue follow these steps
> {code}
> git clone https://github.com/nextflow-io/nextflow.git
> cd nextflow
> CI_GROOVY_VERSION=2.5.0-rc-2 make clean compile test
> {code}
> Curiously, the CI server build is [reporting a slight version of the same
> issue|http://ci.groovy-lang.org/viewLog.html?buildId=49488&tab=buildResultsDiv&buildTypeId=JointBuilds_Nextflow_Groovy25xJointBuild#]
> including sometimes the correct line number instead of -1.
