Hello,

We have tried it also with the following environment.

Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.6.0_45, vendor: Sun Microsystems Inc.
Java home: /usr/lib/jvm/java-6-oracle/jre
Default locale: en_US, platform encoding: ANSI_X3.4-1968
OS name: "linux", version: "3.13.0-36-generic", arch: "amd64", family: "unix"

This time we got only one compilation error:

[ERROR] /home/montoyaedu/plexus-compiler/plexus-compilers/plexus-compiler-javac-errorprone/src/main/java/org/codehaus/plexus/compiler/javac/errorprone/JavacCompilerWithErrorProne.java:[122,32] cannot find symbol

In fact I think it's ok to use 1.7 for compilers other than javac. So I will merge your pr.
Sorry for that!!

[cushon]

Just curious, what was the resolution to this? I couldn't find the PR you mentioned.

Hi,

Well, actually it's a long story.

First we proposed a PR #3 that was not accepted because it used java.nio.file.Paths that is available since 1.7+.

But then when we was trying to fix it, We downloaded 1.6 sdk and realized that the whole project was not anymore 1.6 compliant, then we asked in order to know if it was the desired behaviour, but then our PR #3 was accepted.

Are you trying to compile it with java 1.6?

[cushon]

Thanks for the background. I work on Error Prone - we don't compile it with 1.6 anymore. We only test that it builds with jdk 7 and 8.

The plexus compiler plugin could be made to compile with 1.6, but it sounds like that isn't necessary.
