1
00:00:01,280 --> 00:00:07,210
Okay, so what we have now is
a fairly advanced program.

2
00:00:07,210 --> 00:00:09,096
That's gonna really test
some of your skills,

3
00:00:09,096 --> 00:00:12,510
no I'm just kidding,
it's a simple calculator example here.

4
00:00:12,510 --> 00:00:16,810
And if we just go take a look at
the implementation here we look at main.

5
00:00:16,810 --> 00:00:22,200
Look at the calculator we're gonna see it
does some things that you know how to do.

6
00:00:22,200 --> 00:00:28,170
And if we pop out here it also has tests
because you should always write tests.

7
00:00:28,170 --> 00:00:28,900
Here they are,

8
00:00:28,900 --> 00:00:32,330
there are some tests, verifies that
things are working as they should.

9
00:00:33,630 --> 00:00:35,740
What I'm gonna do is
I'm wanna fork this and

10
00:00:35,740 --> 00:00:39,010
if you wanna follow along you can too
there's a link in the teacher's notes.

11
00:00:39,010 --> 00:00:42,790
I'm wanna fork this to my own personal
account which is what you can do.

12
00:00:42,790 --> 00:00:47,470
And I'm going to go ahead and
I'm going to grab the Clone URL.

13
00:00:47,470 --> 00:00:51,790
When I pop over to my IntelliJ and I'm
gonna check out from Version Control and

14
00:00:51,790 --> 00:00:54,010
check out from GitHub.

15
00:00:54,010 --> 00:00:57,090
I have a two factor authentication
turned on you might not need this.

16
00:00:57,090 --> 00:01:01,380
Don't worry about it if you don't see the
screen, and now I'm going to go ahead and

17
00:01:01,380 --> 00:01:06,120
just paste in the URL that I saw you and
we're gonna get that down here locally.

18
00:01:06,120 --> 00:01:07,640
And since it's a great all.

19
00:01:07,640 --> 00:01:12,540
Should know that's great.

20
00:01:12,540 --> 00:01:13,710
We're gonna go ahead and click finish.

21
00:01:13,710 --> 00:01:19,337
And the project is all here and

22
00:01:19,337 --> 00:01:24,522
we should be able to build.

23
00:01:30,651 --> 00:01:34,102
If we click here and
we do this and we'll go ahead and

24
00:01:34,102 --> 00:01:38,759
build everything here and if we jump
in here and run our Gradle check,

25
00:01:38,759 --> 00:01:42,820
we'll see that all of our test pass,
awesome.

26
00:01:42,820 --> 00:01:43,960
Okay, so now that it's working.

27
00:01:43,960 --> 00:01:46,860
Let's go ahead and
flip over to our Travis CI,

28
00:01:46,860 --> 00:01:50,130
and I'm gonna go ahead and
click Sync Account.

29
00:01:50,130 --> 00:01:53,130
Again, I was up here under My Account.

30
00:01:53,130 --> 00:01:57,300
Now we see that my Java calculator is
ready, I'm gonna go ahead and click it.

31
00:01:57,300 --> 00:02:01,150
Okay, so believe it or
not we're all ready now.

32
00:02:01,150 --> 00:02:05,470
One thing that we need to do is
we need to build that .Travis yml

33
00:02:05,470 --> 00:02:07,020
file that we had discussed.

34
00:02:07,020 --> 00:02:09,080
And if you come down
here to Documentation,

35
00:02:09,080 --> 00:02:13,000
and you scroll down here,
it talks about Language-specific Guides.

36
00:02:13,000 --> 00:02:14,940
And this is pretty awesome you
can see that it does it all for

37
00:02:14,940 --> 00:02:16,370
all these other languages.

38
00:02:16,370 --> 00:02:19,270
We're gonna click on the Java one here.

39
00:02:19,270 --> 00:02:21,990
And the important thing
to note here is that

40
00:02:21,990 --> 00:02:25,860
we're gonna have this language.java and
let's just go ahead.

41
00:02:26,950 --> 00:02:28,290
Let's start that in our IntelliJ.

42
00:02:32,200 --> 00:02:37,066
We come into here and
do a new file called .travis.yml,

43
00:02:37,066 --> 00:02:41,050
okay that's yml,
you had another markup language.

44
00:02:42,340 --> 00:02:45,000
And we wanna automatically add to get.

45
00:02:45,000 --> 00:02:46,790
Wanna closer Gradle window here and

46
00:02:46,790 --> 00:02:50,020
with that said that we needed
to do there we'll language Java.

47
00:02:50,020 --> 00:02:52,280
I'm wanna save that.

48
00:02:52,280 --> 00:02:54,660
Okay, language Java is what we need.

49
00:02:54,660 --> 00:02:57,287
It has a really nice default,
like if you're running mvn,

50
00:02:57,287 --> 00:03:00,090
it has automatic things
that you would normally do.

51
00:03:00,090 --> 00:03:02,610
We normally use Gradle
here on our courses.

52
00:03:02,610 --> 00:03:04,550
It's gonna run Gradle
check which is the test.

53
00:03:04,550 --> 00:03:08,440
It also runs Gradle assemble which we
saw over there, just kind of working.

54
00:03:08,440 --> 00:03:12,250
Also if you run ant and there's dependency
management and you can test against

55
00:03:12,250 --> 00:03:16,990
multiple jdk's, and let's go ahead and
add the jdk that we specifically want.

56
00:03:16,990 --> 00:03:18,390
We want the Oracle jdk, right?

57
00:03:18,390 --> 00:03:20,320
We've been using jdk8.

58
00:03:20,320 --> 00:03:22,714
Back in our yml file.

59
00:03:22,714 --> 00:03:27,256
We'll add jdk:.

60
00:03:27,256 --> 00:03:28,104
And then we'll tab in.

61
00:03:28,104 --> 00:03:33,772
And this is kinda how you do
arrays in this yml language.

62
00:03:33,772 --> 00:03:35,618
Oraclejdk8.

63
00:03:35,618 --> 00:03:36,303
Okay.

64
00:03:36,303 --> 00:03:37,779
That looks good.

65
00:03:37,779 --> 00:03:39,638
Now what we're gonna do.

66
00:03:39,638 --> 00:03:44,790
We have our Travis is already set up,
I'm gonna go into Version Control here.

67
00:03:44,790 --> 00:03:51,030
And when we do this push, it should
automatically, let's say Setup for

68
00:03:51,030 --> 00:03:56,000
Travis CI and go ahead and
do Commit and Push.

69
00:03:57,120 --> 00:03:59,950
And we'll go ahead and Push that file in.

70
00:03:59,950 --> 00:04:03,690
It's gonna go ahead and
trigger a build over a Travis.

71
00:04:03,690 --> 00:04:05,430
Let's take a look and
see what's happening.

72
00:04:05,430 --> 00:04:07,060
If we come back to our home here.

73
00:04:07,060 --> 00:04:12,750
I have some other repositories
that have been running as well and

74
00:04:12,750 --> 00:04:16,020
I come to My Accounts and
I click Java calculator.

75
00:04:16,020 --> 00:04:18,635
Currently it says there's no
build going on let's take a look.

76
00:04:18,635 --> 00:04:19,885
Under branches here.

77
00:04:19,885 --> 00:04:22,435
Here it's building it just
wasn't showing it just yet.

78
00:04:22,435 --> 00:04:24,235
This is kind of slick, so what happens?

79
00:04:24,235 --> 00:04:26,515
Is you get to see what's
actually happening.

80
00:04:26,515 --> 00:04:28,665
You'll see that when it gets into
the state where you can actually

81
00:04:28,665 --> 00:04:31,835
see stuff that pops in over
here over my repositories.

82
00:04:31,835 --> 00:04:36,295
Okay, is going to walk through all of the
information down here of what's going on

83
00:04:36,295 --> 00:04:39,495
in this is again happening
because we pushed that file up.

84
00:04:41,080 --> 00:04:44,010
It's setting up the VM just like it needs.

85
00:04:44,010 --> 00:04:46,330
This gets faster over time and

86
00:04:46,330 --> 00:04:50,230
as this this goes up it will
start collapsing things for you.

87
00:04:50,230 --> 00:04:52,570
I'll show you here in a bit after,
see it collapsed.

88
00:04:52,570 --> 00:04:55,100
You have more information
here should you need it, but

89
00:04:55,100 --> 00:04:59,060
it's gonna show you the things
that's most interesting to you.

90
00:04:59,060 --> 00:05:02,325
Here it is, it's running the gradle
assemble, it's gonna go ahead and download

91
00:05:02,325 --> 00:05:05,720
gradle just like somebody might if they
didn't have gradle on their system.

92
00:05:05,720 --> 00:05:09,160
And remember, this is exactly like what
you would be doing on your machine.

93
00:05:09,160 --> 00:05:12,910
But this is happening on the service,
you normally wouldn't be watching this.

94
00:05:12,910 --> 00:05:15,740
Just kinda wanna show off
what is happening here.

95
00:05:15,740 --> 00:05:17,080
All right, it's got gradle installed.

96
00:05:17,080 --> 00:05:18,587
It's gonna gradle assemble and

97
00:05:18,587 --> 00:05:22,440
if the build passes which it should
because of past locally, right?

98
00:05:22,440 --> 00:05:25,660
Goes compiling, boom that popped out and
then the check happened and

99
00:05:25,660 --> 00:05:30,540
then when it's all said and done,
let's run our test right now.

100
00:05:30,540 --> 00:05:33,930
After it goes ahead downloads
the dependencies, right?

101
00:05:33,930 --> 00:05:36,190
Boom, build successful.

102
00:05:36,190 --> 00:05:39,710
It has turned green and
now if I look at the Current here,

103
00:05:39,710 --> 00:05:43,730
it shows me that we have
a working build at the moment.

104
00:05:43,730 --> 00:05:46,130
That's pretty awesome, right?

105
00:05:46,130 --> 00:05:50,630
I just got an e-mail that had I
set this up to connect the slack,

106
00:05:50,630 --> 00:05:53,620
I also would have got notified in
my slack room this is happening.

107
00:05:53,620 --> 00:05:56,370
Now, one thing that is powerful,
and you've probably seen

108
00:05:56,370 --> 00:05:59,040
these around the internet as you
work on open source projects,

109
00:05:59,040 --> 00:06:00,590
cuz you work on open source projects,
right?

110
00:06:01,600 --> 00:06:02,670
Are these badges.

111
00:06:02,670 --> 00:06:05,520
If you click on this here you
can actually build a new badge.

112
00:06:05,520 --> 00:06:08,490
We wanna say for
the branch master we wanna make sure,

113
00:06:08,490 --> 00:06:10,210
let's do grab Markdown here.

114
00:06:10,210 --> 00:06:12,490
Let's go ahead and copy this.

115
00:06:12,490 --> 00:06:15,248
I'm gonna pop over to my README here.

116
00:06:15,248 --> 00:06:19,290
I'm gonna add this because I am proud
that we know that this is building and

117
00:06:19,290 --> 00:06:22,360
now anybody can look at this and
know that things are working safely.

118
00:06:22,360 --> 00:06:25,580
It's a good way of showing off
that hey things are great here.

119
00:06:27,150 --> 00:06:30,983
Okay, now if we come back over to
our Get repo and when we refresh,

120
00:06:30,983 --> 00:06:34,780
we'll see this pretty little
build passing thing here.

121
00:06:34,780 --> 00:06:36,160
All right, great.

122
00:06:36,160 --> 00:06:38,130
Let's go and add some new test so

123
00:06:38,130 --> 00:06:41,490
we can take a look at what it looks
like when you do a poll request.

124
00:06:41,490 --> 00:06:44,780
Now, the other thing to notice too
is that when I push that read me up.

125
00:06:44,780 --> 00:06:49,220
Look, another log in kicked off,

126
00:06:49,220 --> 00:06:51,347
like here and
see that number two is now going, cool.
