回答1:

Try adding

<dependency>
    <groupId>org.eclipse.jdt.core.compiler</groupId>
    <artifactId>ecj</artifactId>
    <version>4.6.1</version>
    <scope>provided</scope>
</dependency>

to maven pom.xml.

Add the following dependency and save. You may need to restart the application.

<dependency>
    <groupId>org.eclipse.jdt.core.compiler</groupId>
    <artifactId>ecj</artifactId>
    <version>4.6.1</version>
    <scope>provided</scope>
</dependency>
