tycho - Error assembling JAR: A zip file cannot include itself -> [Help 1]

Question

I am adding maven/tycho build to open-source Markdown Editor eclipse-plugin project

I did what I did for several other projects: adding pom.xml for parent, plugin and feature projects. (Sources reference is above, typical pom.xml is below)

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <groupId>com.winterwell.markdown</groupId>
        <artifactId>parent</artifactId>
        <version>0.2.3</version>
    </parent>

    <artifactId>winterwell.markdown</artifactId>
    <version>0.2.3</version>
    <packaging>eclipse-plugin</packaging>

    <name>markdown-editor</name>
    <description>Markdown Editor Plugin for Eclipse</description>

    <build>
        <sourceDirectory>src</sourceDirectory>
    </build>


</project>

However mvn package give somewhat irrelevant error:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:0.18.1:package-plugin (default-package-plugin) on project winterwell.markdown: Error assembling JAR: A zip file cannot include itself -> [Help 1]

There is no definitions for any zip files.

A looked carefully at project and the only difference I see I that it has some .jar dependencies in lib folder.

What the real problem with maven/tycho build could be?

Answer 1

Solution was just to exclude target/,\ from build.properties

source.. = src/
bin.includes = META-INF/,\
               plugin.xml,\
               icons/,\
               .,\
               lib/
