Steps to reproduce

• JaCoCo version: jacoco-0.8.10.zip and jacoco-0.8.11.zip
• Operating system:

Linux VM-16-12-centos 5.4.119-19-0009.11 #1 SMP Wed Oct 5 18:41:07 CST 2022 x86_64 x86_64 x86_64 GNU/Linux

• Tool integration: CLI
• Complete executable reproducer: pingchunzhang
• Steps:

1. start tcp server with jacocoagent

java -javaagent:/mnt/hdd01/zcp/jacoco/lib/jacocoagent.jar=includes=*,output=tcpserver,port=9393,address=localhost,append=true

2. dump exec file

root@VM-0-20-ubuntu:/mnt/hdd01/zcp# /usr/lib/jvm/java-8-openjdk-amd64/bin/java -jar /mnt/hdd01/zcp/jacoco/lib/jacococli.jar dump --address localhost --port 9393 --destfile fe_cov_01.exec
[INFO] Connecting to localhost/127.0.0.1:9393.
[INFO] Writing execution data to /mnt/hdd01/zcp/fe_cov_01.exec.

3. report jacoco report

/usr/lib/jvm/java-8-openjdk-amd64/bin/java -jar /mnt/hdd01/zcp/jacoco/lib/jacococli.jar report fe_cov_01.exec --classfiles /mnt/hdd01/zcp/doris/fe/fe-common/target/classes/*.class  --classfiles /mnt/hdd01/zcp/doris/fe/*/target/classes/org/apache/doris/*/*.class --classfiles /mnt/hdd01/zcp/doris/fe/*/target/classes/org/apache/doris/*/*/*.class --classfiles /mnt/hdd01/zcp/doris/fe/fe-core/target/classes/org/apache/doris/*/*/*/*.class --classfiles /mnt/hdd01/zcp/doris/fe/fe-core/target/classes/doris/segment_v2/*.class --sourcefiles /mnt/hdd01/zcp/doris/fe --html report_test

Expected behaviour

i expect get report correctly, not meet error that Invalid execution data file.

Actual behaviour

Exception in thread "main" java.io.IOException: Invalid execution data file.

(In case of exceptions provide FULL STACKTRACE)

Asterisks (*) in your command are interpreted by your shell

i.e. for

--classfiles /mnt/hdd01/zcp/doris/fe/*/target/classes/org/apache/doris/*/*.class

the real executed command is something like

--classfiles class1.class /mnt/hdd01/zcp/doris/fe/fe-common/target/classes/org/apache/doris/catalog/AnyElementType.class

whereas should be

--classfiles class1.class --classfiles /mnt/hdd01/zcp/doris/fe/fe-common/target/classes/org/apache/doris/catalog/AnyElementType.class

as per documentation https://www.jacoco.org/jacoco/trunk/doc/cli.html every argument such as

/mnt/hdd01/zcp/doris/fe/fe-common/target/classes/org/apache/doris/catalog/AnyElementType.class

without preceding --classfiles is interpreted as exec file and not as class file, resulting in

[INFO] Loading execution data file /mnt/hdd01/zcp/doris/fe/fe-common/target/classes/org/apache/doris/catalog/AnyElementType.class.
Exception in thread "main" java.io.IOException: Invalid execution data file.

as expected.

OK, got it. thank so much.
btw, in my cases, there is so many .class files, if each of it need --classfiles, this command line is particularly large, idon't know Is there a better way？

[Godin]

You don't need to specify each file - you can specify directory.

ok, thank you so much
