Exception opening a Spring Initializr project template

[kz282]

Apache NetBeans version

Apache NetBeans 24 release candidate

What happened

I have created a Spring Boot project on Spring Initializr and opened it both with Netbeans 22 and 24.
Syntax highlight works, syntax check, autocomplete, class import suggestion and some of other features don't.
I can run maven "spring-boot:run" from the goals and it starts the application.

The issue:
When I open a class file from the project I experience issues with lots of Netbeans functionality. Syntax highlight works, syntax check, autocomplete, class import suggestion and some of other features don't. I get the following exception:

Did this work correctly in an earlier version?

No / Don't know

Operating System

Windows 11

JDK

Oracle JDK 17.0.11+7-LTS-207

Anything else

The issue is 100% reproducible every time I open a source file from the downloaded project template.

Add a single dependency for Proof of Error: Lombok.

Something tells me that's your problem. Make sure the version of Lombok is compatible with JDK 23 (the compiler used inside the IDE) and see if the problem goes away.

Probably a duplicate of #7664

My project is running on JDK 17 and I have not installed JDK 23.
Spring Boot 3.3.6 depends on lombok 1.18.36.
According to lombok changelog lombok v1.18.36 is supported on JDK23.

My project is running on JDK 17 and I have not installed JDK 23.

The javac compiler used inside NetBeans is from JDK 23.

I'm not sure where the Lombok version is being specified. The error might suggest that it is not being found. Make the dependency on version 1.18.36 explicit in your pom and try again.

[kz282]

I have found something interesting while editing the pom.xml.
I have deleted the Netbeans cache before each try.
The lombok version does not need to be set explicitly. Spring Boot 3.3.5 depends on lombok 1.18.34, but it works the same:

<dependency>
	<groupId>org.projectlombok</groupId>
	<artifactId>lombok</artifactId>
	<optional>true</optional>
	<!--<version>1.18.36</version>-->
</dependency>

The maven-compiler-plugin configuration of the generated pom.xml breaks the IDE:

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-compiler-plugin</artifactId>
<!-- This configuration breaks the IDE. It is in the Spring Initializr template when Lombok is selected. No version information inside
	<configuration>
		<annotationProcessorPaths>
			<path>
				<groupId>org.projectlombok</groupId>
				<artifactId>lombok</artifactId>
			</path>
		</annotationProcessorPaths>
	</configuration> -->
</plugin>

If I specify the lombok version inside the plugin / configuration / annotationProcessorPaths / path, all IDE feature are working properly. Setting this version field to 1.18.34 works too.

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-compiler-plugin</artifactId>
	<configuration>
		<annotationProcessorPaths>
			<path>
				<groupId>org.projectlombok</groupId>
				<artifactId>lombok</artifactId>
				<version>1.18.36</version>
			</path>
		</annotationProcessorPaths>
	</configuration>
</plugin>

The classpath resolution code is missing quering the DependencyManagment for the plugin version that is correctedin #8057. Please test the nightly build Checks page direct link.

[neilcsmith-net]

Thanks @matthiasblaesing Had just started looking at that having reached the same realisation. Mention of Lombok made me just assume that was the usual issue at first! 🤷
