----------------------------------------
Assignee: Robert Scholte
> Incorrect <compilerArgs> behavior when multiple number <arg>'s have the same
> value
> ----------------------------------------------------------------------------------
>
> Key: MCOMPILER-260
> URL: https://issues.apache.org/jira/browse/MCOMPILER-260
> Project: Maven Compiler Plugin
> Issue Type: Bug
> Affects Versions: 3.3
> Environment: JDK 1.8.0_45
> Maven 3.3.1
> Reporter: Anthony Vanelverdinghe
> Assignee: Robert Scholte
>
> The following configuration:
> {code:xml}
> <compilerArgs>
> <arg>-Xmaxwarns</arg>
> <arg>7</arg>
> <arg>-Xmaxerrs</arg>
> <arg>7</arg>
> </compilerArgs>
> {code}
> always fails, because the last 7 is not passed to javac. However, changing
> any of the numbers so that they're not equal, makes it succeed. Another case
> where it may succeed, is when an additional argument is appended. For example
> the following succeeds:
> {code:xml}
> <compilerArgs>
> <arg>-Xmaxwarns</arg>
> <arg>7</arg>
> <arg>-Xmaxerrs</arg>
> <arg>7</arg>
> <arg>-Werror</arg>
> </compilerArgs>
> {code}
> However, this is not always the case. For example, the following fails:
> {code:xml}
> <compilerArgs>
> <arg>-Xmaxwarns</arg>
> <arg>7</arg>
> <arg>-source</arg>
> <arg>7</arg>
> <arg>-Werror</arg>
> </compilerArgs>
> {code}
> Also note that the numbers do not necessarily have to be adjacent, e.g. the
> following fails as well:
> {code:xml}
> <compilerArgs>
> <arg>-Xmaxwarns</arg>
> <arg>7</arg>
> <arg>-source</arg>
> <arg>1.5</arg>
> <arg>-Xmaxerrs</arg>
> <arg>7</arg>
> </compilerArgs>
> {code}
