I have two projects:

1. An Eclipse project build with pomless Tycho approach
2. A plain Java project build with plain Maven, no OSGI, no Tycho

I need to use some of the bundles from the 1st project in the 2nd project. I tried to install the jar files from the 1st project into a local maven repository using mvn clean install. And tried to reference them from the 2nd project. But I get the following error:

Failed to execute goal on project ...: Could not resolve dependencies for project ...: Failed to collect dependencies at bpms:bpms.util.jdk:jar:0.1.0-SNAPSHOT: Failed to read artifact descriptor for bpms:bpms.util.jdk:jar:0.1.0-SNAPSHOT: Failure to find bpms:bundles:pom:1.0.0-SNAPSHOT in https://repo.maven.apache.org/maven2 was cached in the local repository, the resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]

The bpms.util.jdk-0.1.0-SNAPSHOT.pom file contains the following:

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>bpms</groupId>
    <artifactId>bundles</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>..\.polyglot.pom.tycho</relativePath>
  </parent>
  <artifactId>bpms.util.jdk</artifactId>
  <version>0.1.0-SNAPSHOT</version>
  <packaging>eclipse-plugin</packaging>
  <name>jdk utils</name>
</project>

It seems that the problem is caused by the parent artifact. Is it possible to install my artifacts as standalone artifacts without reference to parent bundles?

What is the right approach? I can't use a pomless Tycho and should define a separate pom.xml for each bundle?

CodePudding user response：

It seems that the simplest approach is to install jar files using mvn install:install-file. Here is a bat-file that could be useful for someone:

@echo off

set MVN_HOME=C:/Tools/apache-maven-3.6.3
set BUNDLES_HOME=C:/Work/workspace-bpms-trunk/bundles
set ECLIPSE_HOME=C:/Tools/eclipse/plugins

for /f "tokens=1,2 delims=:" %%E in (deps.txt) do (
  if exist %BUNDLES_HOME%/%%F (
    for /f "tokens=1,2 delims=: " %%G in (%BUNDLES_HOME%/%%F/META-INF/MANIFEST.MF) do (
      if "%%G" == "Bundle-Version" (
        call mvn install:install-file -DgroupId=%%E -DartifactId=%%F -Dversion=%%~nH-SNAPSHOT -DgeneratePom=true -Dpackaging=jar -Dfile="%BUNDLES_HOME%/%%F/target/%%F-%%~nH-SNAPSHOT.jar"
      )
    )
  ) else (
