Hello everyone,

First of all, Happy New Year 2022 !

Since some weeks I am trying to solve an issue with regard to bundle a JRE along with my product using Maven/Tycho 2.5.0 and JustJ. Unfortunately without success :(

My Eclipse RCP application is based on plug-ins and I would like to include a JRE into it for windows Linux and mac OS.

After following documentation at https://www.eclipse.org/justj/?page=documentation and building my plug-ins based product with Maven/Tycho 2.5.0 I am getting the following error:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-p2-publisher-plugin:2.5.0:publish-products (default-publish-products)
on project *.product: Publisher failed. Verify your target-platform-configuration and executionEnvironment are suitable for proper resolution:
Cannot resolve dependencies of product *.product.

In my product file (*.product) I added the following line in the <plugins> section

<plugin id="org.eclipse.justj.openjdk.hotspot.jre.full"/>

I am using a target file and added there the following lines:

<location includeAllPlatforms="true" includeConfigurePhase="true" includeMode="planner" includeSource="false" type="InstallableUnit">
<repository location="https://download.eclipse.org/justj/jres/11/updates/release/latest/"/>
<unit id="org.eclipse.justj.openjdk.hotspot.jre.base.feature.group" version="0.0.0"/>
</location>

I should mention that my target file has addiional locations, the final target file looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?pde version="3.8"?>
<target name="*.target">
<locations>
<location includeAllPlatforms="true" includeConfigurePhase="true" includeMode="planner" includeSource="false" type="InstallableUnit">
<repository location="https://download.eclipse.org/releases/2021-09/"/>
<unit id="org.eclipse.equinox.sdk.feature.group" version="0.0.0"/>

</location>
<location includeAllPlatforms="true" includeConfigurePhase="true" includeMode="planner" includeSource="false" type="InstallableUnit">
<repository location="https://download.eclipse.org/eclipse/updates/4.21/"/>
<unit id="org.eclipse.platform.ide" version="0.0.0"/>
</location>

<location includeAllPlatforms="true" includeConfigurePhase="true" includeMode="planner" includeSource="false" type="InstallableUnit">
<repository location="https://download.eclipse.org/justj/jres/11/updates/release/latest/"/>
<unit id="org.eclipse.justj.openjdk.hotspot.jre.base.feature.group" version="0.0.0"/>
</location>

</locations>
</target>

According to documentation, by using Tycho versions bigger than 1.7.0, the <resolveWithExecutionEnvironmentConstraints> is not needed,
then, I skipped it an tried to build my product but I am getting the following errors:

C:\Users\com.my.project\eclipse>mvn -Djarsigner.skip=true install

I also tried by adding <resolveWithExecutionEnvironmentConstraints>false</resolveWithExecutionEnvironmentConstraints>

</configuration>
</plugin>


but I am getting the following error:

on project *.product: Publisher failed. Verify your target-platform-configuration and executionEnvironment are suitable for proper resolution: Cannot resolve dependencies of product *.product. See log for details. -> [Help 1]


Does somebody have any hint here?

Thank you very much in advance.

You need this:
	<build>
		<plugins>
			<plugin>
				<groupId>org.eclipse.tycho</groupId>
				<artifactId>tycho-maven-plugin</artifactId>
				<version>${tycho.version}</version>

Hello Ed,

Thank you very much for your answer.

I already tried adding the property <executionEnvironment>org.eclipse.justj.openjdk.hotspot.jre.full-11</executionEnvironment> into the target-platform-configuration section of my master POM file.

So it looks like:

<build>
<plugins>
.
.
.
<groupId>org.eclipse.tycho</groupId>
<artifactId>target-platform-configuration</artifactId>
<version>${tycho-version}</version>
<configuration>
<executionEnvironment>org.eclipse.justj.openjdk.hotspot.jre.full-11</executionEnvironment>
<target>
<artifact>
<groupId>com.my.project</groupId>
<artifactId>*.target</artifactId>
<version>2.6.1-SNAPSHOT</version>
</artifact>
</target>
<environments>
<environment>
<os>win32</os>
<ws>win32</ws>
<arch>x86_64</arch>
</environment>
<environment>
<os>linux</os>
<ws>gtk</ws>
<arch>x86_64</arch>
</environment>
<environment>
<os>macosx</os>
<ws>cocoa</ws>
<arch>x86_64</arch>
</environment>
</environments>
</configuration>
</plugin>
.
.
.
</configuration>
</plugin>

My target file looks like:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?pde version="3.8"?>
<target name="*.target">
<locations>
<location includeAllPlatforms="true" includeConfigurePhase="true" includeMode="planner" includeSource="false" type="InstallableUnit">

<unit id="org.eclipse.equinox.sdk.feature.group" version="0.0.0"/>
<unit id="org.eclipse.cdt.feature.group" version="0.0.0"/>
<unit id="org.eclipse.cdt.sdk.feature.group" version="0.0.0"/>
<unit id="org.eclipse.xtext.sdk.feature.group" version="0.0.0"/>
<unit id="org.eclipse.swtbot.eclipse.feature.group" version="0.0.0"/>
</location>
<location includeAllPlatforms="true" includeConfigurePhase="true" includeMode="planner" includeSource="false" type="InstallableUnit">
<repository location="https://download.eclipse.org/eclipse/updates/4.21/"/>

</location>

<location includeAllPlatforms="true" includeConfigurePhase="true" includeMode="planner" includeSource="false" type="InstallableUnit">

<unit id="org.eclipse.justj.openjdk.hotspot.jre.full.feature.group" version="0.0.0"/>
</location>

</locations>
</target>

and my *.product file contains <plugin id="org.eclipse.justj.openjdk.hotspot.jre.full"/> so it looks like:


<?xml version="1.0" encoding="UTF-8"?>
<?pde version="3.5"?>

<product name="MyProduct" uid="*.product" id="*.product" application="org.eclipse.ui.ide.workbench" version="1.2.0.qualifier" useFeatures="false" includeLaunchers="true">

There are not error dependencies anymore, however my product does not contain any JRE.

I compared my product's output with the one in https://ci.eclipse.org/justj/job/build-sample-product/ and
I do not see folder "org.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64_17.0.0.v20211012-0837" below plugins folder.
Apart from that, eclipse.ini file is also not being updated, it only contains:

-startup
plugins/org.eclipse.equinox.launcher_1.5.600.v20191014-2022.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.1100.v20190907-0426
-consoleLog


I run maven with debug mode and clean command (mvn -Djarsigner.skip=true clean install -X) and realized that the update site "https://download.eclipse.org/justj/jres/11/updates/release/latest/"
is not being called as the other ones defined in *.target file ("https://download.eclipse.org/releases/2021-09/" and "https://download.eclipse.org/eclipse/updates/4.21/").

This is so weird for me because when I look for the update site "https://download.eclipse.org/justj/jres/11/updates/release/latest/" in
the target definition file within my Eclipse development environment (Eclipse IDE for RCP and RAP Developers - 2021-09),
I can see two plugins (org.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64 (11.0.13.v20211116-1829) and
org.eclipse.justj.openjdk.hotspot.jre.full (11.0.13.v20211116-1829)) below the update site after Eclipse resolves target definitions.

I also installed above mentioned plugins locally (window/preferences -> Plug-in Development/Target Platform ) but I get the same result.

Anything I can do?

Maribel

But still in your log I see "[DEBUG] Using execution environment 'JavaSE-11' configured in Bundle-RequiredExecutionEnvironment (first entry)" suggesting that perhaps something is still not right. Note if you look at https://download.eclipse.org/justj/jres/11/updates/release/latest/ in the Repository Explorer view you'll see it has IUs that start with a.jre.* and there is also this specific one:
<unit id='a.jre.org.eclipse.justj.openjdk.hotspot.jre.full' version='11.0.0' singleton='false'>
  <provides size='258'>
    <provided namespace='org.eclipse.equinox.p2.iu' name='a.jre.org.eclipse.justj.openjdk.hotspot.jre.full' version='11.0.0'/>
That's the one that because of "executionEnvironment>org.eclipse.justj.openjdk.hotspot.jre.full-11</executionEnvironment>" should be used as your JRE profile for validating that any package imports of any IUs being installed are satisfied by the JustJ JRE.

I wonder if you should try to get rid of this warning:
[WARNING] includeAllPlatforms='true' and includeMode='planner' are incompatible. ignore includeAllPlatforms flag
setting the former to false?

It's just so much black magic and it's great when it works but it's hard to debug via snippets in the forum.

You're saying this fails with the same error message?

You really need to ensure via -X that the JustJ a.jre.* IU is really being used for the profile/execution-environment....
