systemctl (centos7) broken after install Ant


I am trying to install Ant in a linux container. Should be easy. However, in my scenario, I keep on getting the same problem.
After installing Ant, the systemctl commando does not function anymore.
I receive the following error for any command other then a status command:
Error getting authority: Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: Timeout was reached (g-io-error-quark, 24)
Failed to start ntpd.service: Connection timed out

The polkit package is installed as a dependency.
Did anybody face the same problem or does anybody know how to solve this? Below you will find the specs and the console trail.
I have tried the following:
- reinstall polkit: no change
- manually start polkit: doesn’t work since polkit does not work.
- remove polkit: removes ant and java as dependencies
- search on google: I get lots of old stuff that doesn’t really work. (install dbus)
I believe at this point it’s worth noting that this machine is running as a linux container. I believe there are certain directories (such as proc) that the host system does not allow to change.

Host: Proxmox 4.0 on debian
lxc: centos7, 2 core, 4GB ram, 40GB hdd.

Console trail:
yum install ntp
Loaded plugins: fastestmirror

[ANNOUNCE] CFP open for ApacheCon North America 2016

Community growth starts by talking with those interested in your
project. ApacheCon North America is coming, are you?

We are delighted to announce that the Call For Presentations (CFP) is
now open for ApacheCon North America. You can submit your proposed
sessions at
for big data talks and
for all other topics.

ApacheCon North America will be held in Vancouver, Canada, May 9-13th
2016. ApacheCon has been running every year since 2000, and is the place
to build your project communities.

While we will consider individual talks we prefer to see related
sessions that are likely to draw users and community members. When
submitting your talk work with your project community and with related
communities to come up with a full program that will walk attendees
through the basics and on into mastery of your project in example use
cases. Content that introduces what's new in your latest release is also
of particular interest, especially when it builds upon existing well
know application models. The goal should be to showcase your project in
ways that will attract participants and encourage engagement in your
community, Please remember to involve your whole project community (user
and dev lists) when building content. This is your chance to create a
project specific event within the broader ApacheCon conference.

Content at ApacheCon North America will be cross-promoted as
mini-conferences, such as ApacheCon Big Data, and ApacheCon Mobile, so

How to get list of build files that will be executed for Ant build


I am writing some plugin/hack which needs all the build files that will be
used by Ant for the project [Multi-module project].

Something similar to this

My Project----- build.xml|----- Module 1
      ----- build.xml|----- Module 2
      ----- build.xml

and the build.xml is like this

<project name="test">
 <property name="" value="test"/>

 <ant antfile="module1/build.xml" />
 <ant antfile="module2/build.xml" />

There's echoproperties task which can list out some useful information.

But it doesn't list out anything regarding `antfile` which can call
another build.xml

Any help is appreciated.

Ant Jar Issue

​Dear list

>>The issue:
When jar-ing a module which contains binary certificate file (auth.p12) on CentOS, with Ant 1.9.2, it
seems the p12 file was corrupted after jar compression. (When reading the cerf file with InputStream,
below exception was thrown)

Exception message:

>>The subtle thing:
BUT, if we open the result jar with 7zip on Windows, drag out the p12 file, then drag into the jar again, the
certificate file can be read without problem by InputStream.

>>The guess:
So, 7zip can compress the file correctly, which made me guess it's the jar task which caused the problem.

So I use "jar xvf jarfile" to unjar, then "tar xvf myfile.jar *" to "tar a jar file", and it worked....

>>The question:
Have you guys encounter the same issue, or any suggestions.

Thanks in advance.

Java 9 and javac


Java 9's new module system will add extra options for the "javac" command.
Are there any plans to provide support for this with Ant?

As Jan said, there are no concrete plans for a major re-write of Ant.
We've really "only" been doing maintenance releases with small backwards
compatible improvements and bug fixes for quite some time now.

AW: What are the plans for Ant 2.0?

Yes this is the right list.

We don't have a release plan - next release comes when we (the PMC) decide to release one.
Could be 1-2 years after the last release (like 1.9.5), could be just few weeks (like 1.9.6) - 
depends of the changes.

2.0 would be a version with massive changes in the architecture - I don't see such effords.
So the next version would be 1.9.7 or 1.10.0 ...

What are the plans for Ant 2.0?


I can't find any reference to any plans for 2.0 on the ant site.

Having used ant for a long time, I have some ideas on stuff I'd like to see
in the 2.0 release when it comes out. Is this the right mailing list to
discuss this on?
