Jacoco EOF / Zip error

[Tim Webster]

I'm trying to generate a Jacoco report on a Maven project and can't figure out what's causing this error.  There is nothing special about the project, and the same configuration works on other projects.

the data file is present and looks OK (as far as I can tell)...from the output:

surefireArgLine set to -javaagent:C:\Users\twebster\.m2\repository\org\jacoco\org.jacoco.agent\0.6.3.201306030806\org.jacoco.agent-0.6.3.201306030806-runtime.jar=destfile=D:\intellij-workspaces\my-project-trunk\myproject\target\jacoco-ut.exec

I thought maybe it was trying to instrument/analyze some code not from my project, so I did an <includes/> to only include source from my project.

Hi Tim,

this means that the report goal finds a file in your target directory
which looks like a ZIP file (from its signature) but actually is not a
valid ZIP file.

You might use the includes/excludes parameter to identify the
problematic file.

Cheers,

Hi,

It seems that no matter what I include/exclude, the error still occurs.  Am I using it correctly?  I am doing it in the prepare-agent goal.  I've tried only including a single class, or excluding everything, or only including class files, etc. Nothing works.  There are some .png files in target/classes, I though maybe it was them, but excluding those don't seem to help (exclude **/*.png).

it's a problem that you can't tell what file is causing the error, or what is actually being included/excluded.

I've tried:

<includes>

  <include>**/*.class</include>

<includes>

or 

<includes>

  <include>com.MyClass.class</include>

<includes>

or

<excludes>

  <exclude>**</exclude>

</excludes>

                          <execution>

                                <id>pre-unit-test</id>

                                <goals>

                                    <goal>prepare-agent</goal>

                                </goals>

                                <configuration>

                                    <destFile>target/jacoco-ut.exec</destFile>

                                    <propertyName>surefireArgLine</propertyName>

                                    <includes>

                                        <include>**/*.class</include>

                                    </includes>

                                </configuration>

                            </execution>

I worked it out (after downloading the source, wrapping the exception with some debug information, and building it locally).  It was a spreadsheet file it was complaining about.  To fix it I added the exclusions to the <plugin> section instead of the <execution> section.

Thanks,

Tim
