Plugin does not work from inside Eclipse

[javadch]

I have the following plugin spec in my eClipse POM:

<plugin>
  <groupId>org.openapitools</groupId>
  <artifactId>openapi-generator-maven-plugin</artifactId>
  <version>3.1.0</version>
  <executions>
    <execution>
    <phase>generate-resources</phase>
      <goals>
        <goal>generate</goal>
      </goals>
    <configuration>
      <inputSpec>${project.basedir}/src/main/resources/api.yaml</inputSpec>
      <generatorName>spring</generatorName>
    <configOptions>
    <dateLibrary>joda</dateLibrary>
    <sourceFolder>src/gen/java/main</sourceFolder>
    <modelPackage>services.nano.timex.models</modelPackage>
    <apiPackage>services.nano.timex.apis</apiPackage>
    <invokerPackage>services.nano.timex.invokers</invokerPackage>
    <delegatePattern>true</delegatePattern>
    <hideGenerationTimestamp>false</hideGenerationTimestamp>
  </configOptions>
  <library>spring-boot</library>
</configuration>
</execution>
</executions>
</plugin>

It generates the output artifacts using the mvn clean package command, but does not generate the code form inside Eclipse! The IDE complains about the node saying:

Description Resource Path Location Type Plugin execution not covered by lifecycle configuration: org.openapitools:openapi-generator-maven-plugin:3.1.0:generate (execution: default, phase: generate-resources) pom.xml /timex-backend-api line 34 Maven Project Build Lifecycle Mapping Problem

How can I fix this?

@javadch I could be wrong but I don't think the issue is with the OpenAPI Generator plugin.

Would the following article help?

http://www.eclipse.org/m2e/documentation/m2e-execution-not-covered.html

[jmini]

@wing328 : yes and no. Our maven plugin could be a little bit more eclipse IDE friendly by integrating some additional metadata. This way no error would be displayed in Eclipse IDE.

[wing328]

@jmini 👌 please share more so that the community can help add the metadata.

@jmini 👌 please share more so that the community can help add the metadata.

I guess it is described here how to make the plugin compatible. I will give it a try http://www.eclipse.org/m2e/documentation/m2e-making-maven-plugins-compat.html

edit:

for me the full builds work after adding the lifecycle-mapping, but the source-code-generation also happens in incremental builds even when the openapi-definition has not changed.

To prevent unneccessary builds, the plugin needs to be modified. Before doing smthing it needs to check if the json defintion has changed by using the BuildContext (see https://github.com/sonatype/sisu-build-api/blob/master/src/main/java/org/sonatype/plexus/build/incremental/BuildContext.java).

@andreas-eternach thanks! Let me know if you need help with the PR.

[andreas-eternach]

probably in that source we can see how to use it: https://github.com/highsource/maven-jaxb2-plugin/blob/79b7af0736c5967876cf89ff7967cafe62367bc7/plugin-core/src/main/java/org/jvnet/jaxb2/maven2/RawXJC2Mojo.java

[andreas-eternach]

probably the file
openapi-generator/modules/openapi-generator-maven-plugin/src/main/java/org/openapitools/codegen/plugin/CodeGenMojo.java needs to be updated accordingly.

@javadch after pulling the repo as described by @wing328 you need to

1. cd modules/openapi-generator-maven-plugin
2. mvn install
3. in your eclipse-maven-project update the plugin verion to 3.3.2-SNAPSHOT
4. in eclipse update your eclipse-maven-project by pressing Alt-F5
