exec-maven-plugin with Xtext [message #1856950] Tue, 10 January 2023 16:06 Go to next message

Is there a way of configuring `exec-maven-plugin` to work with Xtext/Tycho?

I have a main file `GenerateTmGrammar` that needs grammar access to my DSL, i.e., it needs to run

Injector inj = new MyDSLStandaloneSetup().createInjectorAndDoEMFRegistration();

MyDSLGrammarAccess grammarAccess = inj.getInstance(MyDSLGrammarAccess.class);
Grammar grammar = grammarAccess.getGrammar();
Set<String> keywords = GrammarUtil.getAllKeywords(grammar);


However, when running a `mvn clean install` on the parent project, I'm getting the following error:
An exception occurred while executing the Java class. com.google.common.util.concurrent.UncheckedExecutionException: java.lang.SecurityException: class "org.eclipse.core.runtime.OperationCanceledException"'s signer information does not match signer information of other classes in the same package

Interestingly, I'm not getting this error when I run `mvn clean install` on the actual submodule containing `GenerateTmGrammar.java`.

Before I imported anything related to Xtext the plugin was running fine.

Does anybody have experience with setting this up? Any solutions/workarounds?

`exec-maven-plugin` configuration:
<plugin>
	<groupId>org.codehaus.mojo</groupId>
	<artifactId>exec-maven-plugin</artifactId>
	<version>3.1.0</version>
	<executions>
		<execution>
			<id>Generate TextMate grammar json file</id>
			<phase>prepare-package</phase>
			<goals>
				 <goal>java</goal>
			 </goals>
			<configuration>
				<mainClass>com.example.mydsl.ide.textmate.GenerateTmLanguage</mainClass>
				<arguments>
					<argument>${project.basedir}/mydsl.tmLanguage.yaml</argument>
					<argument>${project.basedir}/src-gen/syntaxes/mydsl.tmLanguage.json</argument>
				</arguments>
				<classpathScope>compile</classpathScope>
			</configuration>
		</execution>
	</executions>
</plugin>


Note that I've added `<classpathScope>compile</classpathScope>`. Before that, it wasn't finding my dependency on SnakeYAML, which I added to the target file of my project. I'm not sure why.

have no idea but

An exception occurred while executing the Java class. com.google.common.util.concurrent.UncheckedExecutionException: java.lang.SecurityException: class "org.eclipse.core.runtime.OperationCanceledException"'s signer information does not match signer information of other classes in the same package

this looks like an inconsistent use of ecore.runtime and equinox.common.
by using matching explicit versions for both the problem should vanish

Thanks! Adding these two dependencies to the plugin actually solved it.

After that, I noticed that I actually had some dependencies defined in Maven that were conflicting with Tycho. Once I replaced all explicit Maven dependencies with the corresponding target platform/Tycho dependencies, I could run exec-maven-plugin without the additional dependencies. So the actual cause was a problem in my Maven configuration.

Hm, although now I'm getting a `FileSystemNotFoundException: Provider "bundleresource" not installed` exception while running unit tests. @Christian Dietrich, do you have an idea in which dependency file system support for `bundleresource` is defined?

Tests are fine when I run them in Eclipse.

can you try with a clean maven repo -Dmaven.repo.local=somedir
what is the complete stacktrace and what does the code that crashes do?

Never mind, I got a workaround. Just opened the resource as a stream instead of opening it as a URL and converting it to a file path.

Thanks for the help!

so its about plugin tests, not (pure) unit tests
