Maven error “Cannot resolve project dependencies:” — “org.eclipse.jst.web_sdk.feature.feature.group”

Question

I was following the instructions at Import into Eclipse and Set up Development Environment when I got to the step that says

2. Run the setup.sh script if you havn't created the target platform: sh setup.sh.

It is to be run in terminal on macOS.

I received the following error messages:

[ERROR] Cannot resolve project dependencies:

[ERROR] Software being installed: com.amazonaws.eclipse.devide raw:1.0.0.'SNAPSHOT'/format(n[.n=0;[.n=0;[-S]]]):1.0.0-SNAPSHOT

It looks like I need to add "org.eclipse.jst.web_sdk.feature.feature.group" as a dependency, but I'm not able to find that module to download.

This is what is in the pom.xml file originally:

<project>
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.amazonaws.eclipse</groupId>
    <artifactId>com.amazonaws.eclipse.releng</artifactId>
    <version>1.0.0-SNAPSHOT</version>
  </parent>
  <artifactId>com.amazonaws.eclipse.devide</artifactId>
  <version>1.0.0-SNAPSHOT</version>
  <packaging>eclipse-repository</packaging>

  <build>
    <plugins>
      <plugin>
        <groupId>org.eclipse.tycho</groupId>
        <artifactId>tycho-p2-repository-plugin</artifactId>
        <version>${tycho.version}</version>
        <configuration>
          <includeAllDependencies>true</includeAllDependencies>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

This is the pom.xml file after I added content to it:

<project>
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.amazonaws.eclipse</groupId>
    <artifactId>com.amazonaws.eclipse.releng</artifactId>
    <version>1.0.0-SNAPSHOT</version>
  </parent>
  <artifactId>com.amazonaws.eclipse.devide</artifactId>
  <version>1.0.0-SNAPSHOT</version>
  <packaging>eclipse-repository</packaging>

  <dependencies>
    <dependency>
      <groupId>com.amazonaws.eclipse</groupId>
      <artifactId>org.eclipse.jst.web_sdk.feature.feature.group</artifactId>
      <version>1.0.0</version>
    </dependency>
  </dependencies>

  <build>
    <plugins>
      <plugin>
        <groupId>org.eclipse.tycho</groupId>
        <artifactId>tycho-p2-repository-plugin</artifactId>
        <version>${tycho.version}</version>
        <configuration>
          <includeAllDependencies>true</includeAllDependencies>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

This is a screenshot of the Project Explorer in Eclipse. I don't have any projects, just this workspace.

This is the pane titled "Markers" at the bottom of the Eclipse IDE:

What do I need to do to successfully run "sh setup.sh" as the step instructs?

Answer 1

This project is different from other project. it is an eclipse plugin project. First of all, after cloning this project, go to command prompt pointing to the directory of this plugin project and run the following command.

mvn clean package .

Once the build is successful, import as plugin project in eclipse. This is the normal way of importing eclipse plugin project. It is recommended to go through the ReadMe.md file in the github link. https://github.com/aws/aws-toolkit-eclipse

I will suggest, first go through the following helpful links about tycho and how to configure and develop eclipse plugin.

https://wiki.eclipse.org/Developing_Tycho https://www.vogella.com/tutorials/EclipseTycho/article.html

You can also refer to the following stackoverflow link.
