pom file parent project

[isakovarseniy]

Hi

I have following maven structure

parent-project
       |-jsweet-project

if I do following :

cd parent-project
mvn clean install   

jsweet use parent-project as current directory instead of parent-project\jsweet-project
So all jsweet generated files will be created under parent project. Also "jsweetconfig.json" file is tried to be resolve under paren directory

Partially I have resolve the issue by following configuration

			<plugin>
				<groupId>org.jsweet</groupId>
				<artifactId>jsweet-maven-plugin</artifactId>
				<version>${version.jsweet.transpiler}</version>
				<executions>
					<execution>
						<id>generate-js</id>
						<phase>generate-sources</phase>
						<goals>
							<goal>jsweet</goal>
						</goals>
						<configuration>
							<verbose>true</verbose>
							<outDir>${project.basedir}/src/main/resources/META-INF/resources/webjars/${project.artifactId}/${project.version}</outDir>
							<dtsOut>${project.basedir}/src/main/resources/META-INF/resources/typings/${project.artifactId}/${project.version}</dtsOut>
							<tsOut>${project.basedir}/target</tsOut>
							<workingDir>${project.basedir}</workingDir>
							<declaration>true</declaration>
							<sourceMap>true</sourceMap>
							<targetVersion>ES6</targetVersion>
							<module>es2015</module>
						</configuration>
					</execution>
				</executions>
			</plugin>

But I cannot configure location of "jsweetconfig.json" file

Thanks

Fixed through 77536a0

Could you please try again and close? Thanks

[lgrignon]

Note: version of the plugin 2.0.1-SNAPSHOT

[isakovarseniy]

Hi
No it is not working. I have configuration file and customization adapter inside of jsweet-project.
During maven execution jsweet cannot find Adapter.

Thanks

Hi,
Could you provide the stacktrace please?
I will give a look now

Indeed, this bug remained unfix. It should be ok by now through e9774f8931a5d4ca4d692b48704fdb27a1936418 and 89aa3788744dcd3819636c1fca735348cff37276
I just deployed it to 2.0.1-SNAPSHOT, could you please give a try?

[isakovarseniy]

No still is not working

Class JSweetTranspiler
Line 501
Use following

		new ExtensionManager(baseDirectory.getAbsolutePath() + File.separator + JSweetConfig.EXTENSION_DIR).checkAndCompileExtension(this.workingDir, classPath);

[lgrignon]

Fixed with 5ea287763c103a6a2137a755dfa0aa3c6da82763
and deployed to 2.0.1-SNAPSHOT

I hope it's the last occurrence :)

[isakovarseniy]

Still an issue.
I have figured out. Problem in ExtensionManager
Variable "foundExtension" always false. It is never updates class path.
If I change code to force class path update jsweet is working,

	private void initExtensionClassPath() {
		if (!extensionDir.exists()) {
			return;
		}
		try {
			if (!(PrinterAdapter.class.getClassLoader() instanceof URLClassLoader)) {
				throw new RuntimeException(
						"local extensions are not supported in this environment, please use a packaged extension");
			}
			URLClassLoader urlClassLoader = (URLClassLoader) PrinterAdapter.class.getClassLoader();
			Method method = URLClassLoader.class.getDeclaredMethod("addURL", URL.class);
			method.setAccessible(true);
			boolean foundExtension = false;
			for (URL url : urlClassLoader.getURLs()) {
				if (url.getPath().endsWith("/" + JSweetConfig.EXTENSION_DIR)) {
					foundExtension = true;
					break;
				}
			}
			if (!foundExtension) {
				method.invoke(urlClassLoader, new File(JSweetConfig.EXTENSION_DIR).toURI().toURL());
				logger.debug("updated classpath with: " + new File(JSweetConfig.EXTENSION_DIR).toURI().toURL());
			}
		} catch (Exception e) {
			throw new RuntimeException("fail to initalize extension classpath", e);
		}
	}

So method will be like this

	private void initExtensionClassPath() {
		if (!extensionDir.exists()) {
			return;
		}
		try {
			if (!(PrinterAdapter.class.getClassLoader() instanceof URLClassLoader)) {
				throw new RuntimeException(
						"local extensions are not supported in this environment, please use a packaged extension");
			}
			URLClassLoader urlClassLoader = (URLClassLoader) PrinterAdapter.class.getClassLoader();
			Method method = URLClassLoader.class.getDeclaredMethod("addURL", URL.class);
			method.setAccessible(true);

			method.invoke(urlClassLoader, this.extensionDir.toURI().toURL());
			logger.debug("updated classpath with: " + this.extensionDir.toURI().toURL());
		} catch (Exception e) {
			throw new RuntimeException("fail to initalize extension classpath", e);
		}
	}

Is it possible that you share your project or a similar one on a Github I could clone? If not possible, I will try to create a sample project for JSweet with maven parent pom and fix all remaining problems

[isakovarseniy]

This is link on my project https://github.com/isakovarseniy/tura . You need switch to version 4.3.0.

>cd platform/platform-ts/
>mvnDebug clean install

if you run mvnDebug you can connect with remote debugger Or you can run just

>mvn clean install

[lgrignon]

Hello @isakovarseniy I just deployed a new version of JSweet, with which I succeeded to build your project. I had some remaining errors in your unit tests runs but I think this is not related, please tell me if you think this way as well.

By the way, you were right, it was more of a JSweet issue than a JSweet maven plugin's issue ;)

Please close if ok for you

[isakovarseniy]

Thanks It works

[courteous]

So what is the solution to this. I am getting the exact same error described here. My pluggin version looks like that

	<plugin>
		<groupId>org.jsweet</groupId>
		<artifactId>jsweet-maven-plugin</artifactId>
<!-- 		<version>2.0.0-rc1</version> -->
		<version>2.0.1-SNAPSHOT</version>
		
		<configuration>
			<sourceMap>true</sourceMap>
			<declaration>true</declaration>
			<outDir>target/js</outDir>
			<dtsOut>target/ts</dtsOut>
			<workingDir>${project.basedir}</workingDir>
			<verbose>true</verbose>
			
			<!-- Do not compile the TypeScript output (let an external TypeScript compiler do so). -->
			<tsOnly>false</tsOnly>
			
			<excludes> 
						
					   
			</excludes>
			
			<targetVersion>ES6</targetVersion>
			<module>es2015</module>

			<bundle>false</bundle>
			
			<executions>

					<phase>generate-sources</phase>
					<goals>
						<goal>jsweet</goal>
					</goals>
				</execution>
			</executions>
						
		</configuration>

	</plugin>

and I am currenly using those two version. lgrignon can you please share what did you do in order to fix the error.

		<dependency>
			<groupId>org.jsweet</groupId>
			<artifactId>jsweet-core</artifactId>
			<version>5-20170726</version>
		</dependency>


		<dependency>
			<groupId>org.jsweet</groupId>
			<artifactId>jsweet-transpiler</artifactId>
			<version>2.0.1-SNAPSHOT</version>
		</dependency>

I have the exact same project strurcture as the one described here Configure path to jsweetconfig.json and jsweet_extension but i still getting the same error. my jsweetconfig.json looks like

{
adapters: [ "ByteBufferAdapter", "TimeAdapter"]
}

[isakovarseniy]

Remove extension.json file.
Remove ByteBufferAdapter.class, TimeAdapter.class

[lgrignon]

Thanks @isakovarseniy

@courteous does it work for you?

[courteous]

i have commented the following lines in my pom and then it started working agian

<!-- 			<workingDir>${project.basedir}</workingDir> -->
<!-- 			<tsOut>${project.basedir}/target</tsOut> -->

simply removing the adapters and extension.json file did not worked for me.
