Eclipse run-as 工作时插件失败

问题描述

当我安装 jar 时，eclipse 应用程序（尤其是 knime）有哪些“无法创建”类的方法。该类似乎没有任何问题，因为它在 eclipse 中使用 run as tool 运行。当我导出为插件或创建更新站点时，最终的插件失败了。类文件位于此错误代码段下方。

无法创建来自插件“org.knime.examples.numberformatter”的错误 RepositoryManager 节点“org.knime.examples.numberformatter.NumberFormatterNodeFactory”。无法激活对应的插件包！

package org.knime.examples.numberformatter;

import org.knime.core.node.NodeDialogPane;
import org.knime.core.node.NodeFactory;
import org.knime.core.node.NodeView;

/**
 * This is an example implementation of the node factory of the
 * "NumberFormatterNode".
 * 
 * The node factory creates all classes the make up a node. Furthermore,it specifies if the
 * node has views or a dialog (both are optional).

public class NumberFormatterNodeFactory extends NodeFactory<NumberFormatterNodeModel> {

    /**
     * {@inheritDoc}
     */
    @Override
    public NumberFormatterNodeModel createNodeModel() {
        // Create and return a new node model.
        return new NumberFormatterNodeModel();
    }

    /**
     * {@inheritDoc}
     */
    @Override
    public int getNrNodeViews() {
        // The number of views the node should have,in this cases there is none.
        return 0;
    }

    /**
     * {@inheritDoc}
     */
    @Override
    public NodeView<NumberFormatterNodeModel> createNodeView(final int viewIndex,final NumberFormatterNodeModel nodeModel) {
        // We return null as this example node does not provide a view. Also see "getNrNodeViews()".
        return null;
    }

    /**
     * {@inheritDoc}
     */
    @Override
    public boolean hasDialog() {
        // Indication whether the node has a dialog or not.
        return true;
    }

    /**
     * {@inheritDoc}
     */
    @Override
    public NodeDialogPane createNodeDialogPane() {
        // This example node has a dialog,hence we create and return it here. Also see "hasDialog()".
        return new NumberFormatterNodeDialog();
    }

}

解决方法

解决了。目标项目jre需要匹配knime jre版本。
