            Bug ID: 59379
           Summary: Get task not quiet if dest file exists
           Product: Ant
           Version: 1.9.6
          Hardware: PC
                OS: other

          Priority: P2

Test case

# Overview

The Get task is not quiet when the `dest' file exists and the `quiet' and
`skipexisting' attributes are set to `true'; it displays a message like this:

[get] Destination already exists (skipping): /tmp/ant-get-test/mylib.jar

# Steps to Reproduce

1. Save the attached build.xml file to the directory /tmp/ant-get-test (or
wherever)

2. Run Ant in the directory:

   $ ant

# Actual Results

Buildfile: /tmp/ant-get-test/build.xml

build:
    [touch] Creating /tmp/ant-get-test/mylib.jar
      [get] Destination already exists (skipping): /tmp/ant-get-test/mylib.jar

BUILD SUCCESSFUL
Total time: 0 seconds

# Expected Results

The Get task should not write the message about the destination file already
existing because the `quiet' attribute is set to `true':

Buildfile: /tmp/ant-get-test/build.xml

build:
    [touch] Creating /tmp/ant-get-test/mylib.jar

BUILD SUCCESSFUL
Total time: 0 seconds

# Build Date & Hardware

Ant 1.9.6 on OS X El Capitan (10.11.4).

# Additional Builds and Platforms

I haven't tested on other platforms, but the problem probably exists
everywhere.

# Additional Information

Looking at the source code for the Get task from the Git master branch, it
seems like one fix would be to only call the `log' method if the `quiet'
attribute is not set to `true' as in the attached get-quiet-skip-existing.diff
(untested).

Another approach would be to change the `log(String, int)' method to use a
different conditional for the `msgLevel' test.  Right now, it uses `msgLevel >=
Project.MSG_ERR', but in Project, MSG_ERR, MSG_WARN, MSG_INFO, MSG_VERBOSE, and
MSG_DEBUG are set to 0-4, respectively, so the `msgLevel >= Project.MSG_ERR'
test will always evaluate to true (and hence the super.log call will always be
made) unless a value less than 0 is specified (i.e. not one of the Project
class constants).
