Could not find artifact com.sun:tools:jar:0

问题

I'm trying to use checkstyle and findbugs by doing mvn checkstyle:checkstyle but I have this error This error

[ERROR] Failed to execute goal on project my-project: Could not resolve dependencies for project default:my-project:jar:1.1: Could not find artifact com.sun:tools:jar:0 at specified path C:\Program Files\Java\jdk-11.0.2/../lib/tools.jar -> [Help 1]

I do not have a tools.jar into my JDK (i have jdk-11.0.2).

I'm on it since 2H, please help :/

回答1:

You're on JDK 11.
The JEP 220 removed both tools.jar and rt.jar from the lib folder.

Removed: rt.jar and tools.jar

The class and resource files previously stored in lib/rt.jar, lib/tools.jar, lib/dt.jar, and various other internal JAR files are now stored in a more efficient format in implementation-specific files in the lib directory. The format of these files is not specified and is subject to change without notice.

To upgrade Checkstyle use

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-checkstyle-plugin</artifactId>
   <version>3.0.0</version>
   <dependencies>
     <dependency>
        <groupId>com.puppycrawl.tools</groupId>
        <artifactId>checkstyle</artifactId>
        <version>8.18</version>
     </dependency>
   </dependencies>
</plugin>

See the inner dependency block.
