jacoco the html incorrect

[Liangbin Dai]

Hi marc：

   I get a html like this , I donot know why ,

  I hava already checkeck the sessions , it has the coverage the  classes which I calls manually.

  but I donot know why html the coverage report seems incorrect , the code should execute in order ,but the html seems incorrect because the code execute uncontinues .

  I guess the problem is due to .exec data or classes files or source files ,but I donot know how to make sure and config out what the problem.

  can you help me ,thanks

Hi,

this looks really strange. Only the first line is highligted as covered,
right?

Can you please provide some information about your setup:

1) How do you create the report (Maven, Ant, Eclipse, ...)?
2) What exact version of JaCoCo are you using (see footer of report)?
3) How do you compile your class files? What compiler vendor/version are
you using?
4) Do you process you class files after compiling (e.g. for obfuscation)

Regards,
-marc

Thanks for your relpy, Mars.I will answer your problem and tell my setup detailly.

1)I use ant ,the ant vresion is Apache Ant(TM) version 1.9.7

2)the jacoco version is  JaCoCo 0.7.8.201606240924

3

a)the web application which  I collect covereage data is a jar ,

the jar is got by maven command :mvn clean package,the compiler is maven-compiler-plugin:3.1:compile

we startup the application use command:

nohup java -jar -Xmx1536m -XX:MaxPermSize=512M -javaagent:/opt/jacocoagent.jar=includes=*,output=tcpserver,port=10003,address=1127.0.0.1  -Djava.security.egd=file:/dev/./urandom server-3.2.0-SNAPSHOT.jar --server.port=9001 --shell.ssh.port=2002 --spring.profiles.active=build > nohup.log &

I restart my application after add the javaagent 

b)I donot know how to configure the application ,so I unzip the server-3.2.0-SNAPSHOT.jar ,and delete the lib file(if I donot delete the lib file the command ant report will show error message  Error while creating report     Caused by: java.io.IOException: Error while analyzing lib/bcprov-jdk16-1.46.jar@org/bouncycastle/LICENSE.class. 

Caused by: java.lang.IllegalStateException: Can't add different class with same name: org/bouncycastle/LICENSE  )

and this is my build.xml

( someone  tells I donot need unzip the jar file ,but I donnt know how to configuer it .I have used jacoco with ant  before,  but it is a war applicatiuon ,I can get the classes easily.)

4) I just unzip the jar file , delete the jar and lib file ,and donot modily the clsses manual.

I can tell you what I do after I see the html report

a）first,I calls an http interface manual, the use ant dump ,I found the .exec file size increased

b) I checked the application ,the source file is same with the branch code(git pull) and the jar applicaion is same with the branch code .

c) I checked the session ,it show the classes I calls , but the detail  html  page is still like the picture I show you .but somecode of the applicaion seems right(the highted code is continues)

sorry , I will show you my idea (maybe it is incorrect )

1)I guess the .exec data is right ,because when I call a http interface the .exec file size grows,I guess is has collected the coverage data

2) if the .exec data is right ,it just seems the html report just shows incorrect ,because to produce the report I will provider classes files 、 source files and .exec data .The relation betwwen them is .exec data is dumped with running classed ,and the classes file can map the source files ,if the .exec data has collected the coverage ,either the .exec data is not matched with classes file ,or the classes files is not matched with the source code. but when I clicked the class in the html report (right conner) is seems the classes file and source file mapping is right.

and I guess maybe my applicaion use some jars affecting the .exec data ~

waiting your reply
