Eclipse is showing this error
Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-jar-plugin:2.4:jar (execution: make-jar, phase: compile)
It shows the error against the
<execution> line in one of our POMs, an extract of which is below.
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <build> ... <plugins> ... <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.4</version> <executions> <!-- Create shared ViewController JAR file which is used by MYPROJECT-API-V1 --> <execution> <id>make-jar</id> <phase>compile</phase> <goals> <goal>jar</goal> </goals> </execution> ...
I only notice this error in Ecliipse Luna - it was not showing in Eclipse Kepler. Further, I can still build OK from the command line and even Eclipse still builds the project.
The fix was surprisingly easy. I select the quick fix:
Discover new m2e connectors. Nothing came up, but when I clicked on FINISH, I found that Eclipse was indeed updating the m2e Connectors. I let it happen, re-started Eclipse, and the error disappeared.
