"Plugin execution not covered" error after fixing an "'build.plugins.plugin.version' is missing" warning for the tycho-packaging-plugin

I use tycho-packaging-plugin to set the output folder for the jar. Here is shortened version of my pom:

<properties>
    <tycho-version>0.21.0</tycho-version>
</properties>
<build>
  <plugins>
    <plugin>
        <groupId>org.eclipse.tycho</groupId>
        <artifactId>tycho-maven-plugin</artifactId>
        <version>${tycho-version}</version>
        <extensions>true</extensions>
    </plugin>
    <plugin>
        <groupId>org.eclipse.tycho</groupId>
        <artifactId>tycho-packaging-plugin</artifactId>
        <configuration>
            <buildDirectory>${project.build.directory}/plugins</buildDirectory>
        </configuration>
    </plugin>
  </plugins>
</build>

I get a warning if I execute maven-install:

[WARNING] Some problems were encountered while building the effective model for com.foo.bar.devtool:com.foo.bar.devtool:eclipse-plugin:0.0.1-SNAPSHOT
[WARNING] 'build.plugins.plugin.version' for org.eclipse.tycho:tycho-packaging-plugin is missing. @ line 44, column 21
[WARNING] 
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING] 
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.

I follow the advice of the warning and modify the pom:

<plugin>
    <groupId>org.eclipse.tycho</groupId>
    <artifactId>tycho-packaging-plugin</artifactId>
    <version>${tycho-version}</version>
    <configuration>
        <buildDirectory>${project.build.directory}/plugins</buildDirectory>
    </configuration>
</plugin>

And then I get errors after saving the file:

Multiple annotations found at this line:
    - Plugin execution not covered by lifecycle configuration: org.eclipse.tycho:tycho-packaging-plugin:${tycho.version}:build-qualifier (execution: default-build-qualifier, phase: 
     validate)
    - Plugin execution not covered by lifecycle configuration: org.eclipse.tycho:tycho-packaging-plugin:${tycho.version}:validate-version (execution: default-validate-version, 
     phase: validate)
    - Plugin execution not covered by lifecycle configuration: org.eclipse.tycho:tycho-packaging-plugin:${tycho.version}:validate-id (execution: default-validate-id, phase: validate)

How to resolve the issue and to avoid getting both warnings and errors?

Solution

  • You don't have the Tycho Project Configorator for m2e installed, so m2e doesn't know if it should execute the listed goals as part of the incremental build in Eclipse.

    To install the connectors, trigger the quick fix of the errors (e.g. from the Problems view) and select Discover new m2e connectors.
