Maciej Gorywoda created MPLUGIN-373:
---------------------------------------
Summary: Java 16 features not supported by
maven-plugin-plugin:3.6.1
Key: MPLUGIN-373
URL: https://issues.apache.org/jira/browse/MPLUGIN-373
Project: Maven Plugin Tools
Issue Type: Bug
Components: Plugin Plugin
Affects Versions: 3.6.1
Environment: Linux Mint 21.0 Cinnamon, Linux Kernel 5.4.0-71-generic,
arch amd64, OpenJDK 16.0.1, Apache Maven 3.6.3.
Reporter: Maciej Gorywoda
Even though compilation works, `mvn install` fails with:
```
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-plugin-plugin:3.6.1:descriptor
(default-descriptor) on project maven-plugin-minimal: Execution
default-descriptor of goal
org.apache.maven.plugins:maven-plugin-plugin:3.6.1:descriptor failed: syntax
error @[27,1] in
file:/home/makingthematrix/workspace/maven-plugin-minimal/src/main/java/io/makingthematrix/MinimalMojo.java
-> [Help 1]
```
That syntax error @[27,1] is
```
{color:#0033b3}record {color}{color:#000000}KaBoom{color}({color:#000000}String
{color}foo) {}
```
Tested on openjdk-16 and graalvm-21.1.0 for Java 16.
{color:#0033b3}maven-compiler-plugin version: 3.8.1
{color}
{color:#0033b3}maven-plugin-plugin version: 3.6.1{color}
I made a minimal example and put it on GitHub:
