XMLBeans 無法加載 SchemaTypeSystem。 無法加載名為 schemaorg_apache_xmlbeans.system 的 class

Question

我正在嘗試使用從 github 克隆的項目（IntellijJ 文件-> 新建-> 版本控制中的項目）運行 SoapUI：

git clone https://github.com/SmartBear/soapui.git

然后我運行 maven 編譯，它沒有錯誤。 但是當我嘗試運行該應用程序時，出現以下錯誤：

15:20:40,429 WARN  [SoapUI] Missing folder [C:\%USERPROFILE%\IdeaProjects\soapui\ext] for external libraries

這是 POM 的鏈接： https://github.com/SmartBear/soapui/blob/next/soapui/pom.xml

在閱讀了一些類似的問題后，我認為 POM 有問題，但我不知道是什么問題。 有什么提示嗎？

嗨，我遇到了同樣的問題並修復了它。

它發生在這里。

settingsDocument = SoapuiSettingsDocumentConfig.Factory.newInstance();

public static final class Factory
{
    public static com.eviware.soapui.config.SoapuiSettingsDocumentConfig newInstance() {
      return (com.eviware.soapui.config.SoapuiSettingsDocumentConfig) org.apache.xmlbeans.XmlBeans.getContextTypeLoader().newInstance( type, null ); }

根本原因就是這個。

無法加載此 class。 “org.apache.xmlbeans.XmlBeans.getContextTypeLoader()”

這個解決方案是一個添加 jar-with-dependencies 插件。

使用 XmlBeans 生成的類時出錯

http://maven.apache.org/plugins/maven-assembly-plugin/descriptor-refs.html#jar-with-dependencies

你必須在 pom.xml 中添加兩個塊

            <build>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-assembly-plugin</artifactId>
                    <version>3.3.0</version>
                    <configuration>
                        <archive>
                            <manifest>
                                <mainClass>fully.qualified.MainClass</mainClass>
                            </manifest>
                        </archive>
                        <descriptorRefs>
                            <descriptorRef>jar-with-dependencies</descriptorRef>
                        </descriptorRefs>
                    </configuration>
                </plugin>
            </plugins>
        </buid>

和

        <dependency>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>3.3.0</version>
    </dependency>
