Classpath too long in electron-vaadin.bat

[bb8-droid]

When building the app with windows 64bit I run into this issue that the server could not start. I figured out, that a line in electron-vaadin.bat is too long. It is where you set the classpath:

set CLASSPATH=%APP_HOME%\lib\electron-java-app-0.2.jar;%APP_HOME%\lib\vaadin-core-14.1.17.jar;%APP_HOME%\lib\javax-websocket-server-impl-9.4.27.v20200227.jar;%APP_HOME%\lib\jetty-annotations-9.4.27.v20200227.jar;%APP_HOME%\lib\jetty-plus-9.4.27.v20200227.jar;%APP_HOME%\lib\jetty-webapp-9.4.27.v20200227.jar;%APP_HOME%\lib\websocket-server-9.4.27.v20200227.jar;%APP_HOME%\lib\jetty-servlet-9.4.27.v20200227.jar;%APP_HOME%\lib\jetty-security-9.4.27.v20200227.jar;%APP_HOME%\lib\jetty-server-9.4.27.v20200227.jar;%APP_HOME%\lib\websocket-servlet-9.4.27.v20200227.jar;%APP_HOME%\lib\javax.servlet-api-3.1.0.jar;%APP_HOME%\lib\logback-classic-1.2.3.jar;%APP_HOME%\lib\jetty-continuation-9.4.27.v20200227.jar;%APP_HOME%\lib\flow-html-components-2.1.5.jar;%APP_HOME%\lib\flow-data-2.1.5.jar;%APP_HOME%\lib\flow-dnd-2.1.5.jar;%APP_HOME%\lib\flow-server-2.1.5.jar;%APP_HOME%\lib\flow-push-2.1.5.jar;%APP_HOME%\lib\flow-client-2.1.5.jar;%APP_HOME%\lib\vaadin-lumo-theme-2.1.5.jar;%APP_HOME%\lib\vaadin-material-theme-2.1.5.jar;%APP_HOME%\lib\vaadin-accordion-flow-2.0.0.jar;%APP_HOME%\lib\vaadin-app-layout-flow-2.0.4.jar;%APP_HOME%\lib\vaadin-button-flow-2.0.2.jar;%APP_HOME%\lib\vaadin-checkbox-flow-2.0.3.jar;%APP_HOME%\lib\vaadin-combo-box-flow-3.0.6.jar;%APP_HOME%\lib\vaadin-date-picker-flow-2.0.6.jar;%APP_HOME%\lib\vaadin-time-picker-flow-2.0.3.jar;%APP_HOME%\lib\vaadin-select-flow-2.0.3.jar;%APP_HOME%\lib\vaadin-dialog-flow-2.0.1.jar;%APP_HOME%\lib\vaadin-details-flow-2.0.0.jar;%APP_HOME%\lib\vaadin-form-layout-flow-2.0.2.jar;%APP_HOME%\lib\vaadin-grid-flow-4.1.0.jar;%APP_HOME%\lib\vaadin-icons-flow-2.0.1.jar;%APP_HOME%\lib\vaadin-iron-list-flow-2.0.0.jar;%APP_HOME%\lib\vaadin-list-box-flow-2.1.1.jar;%APP_HOME%\lib\vaadin-notification-flow-2.0.0.jar;%APP_HOME%\lib\vaadin-ordered-layout-flow-2.0.0.jar;%APP_HOME%\lib\vaadin-progress-bar-flow-2.0.2.jar;%APP_HOME%\lib\vaadin-radio-button-flow-2.0.2.jar;%APP_HOME%\lib\vaadin-split-layout-flow-2.0.3.jar;%APP_HOME%\lib\vaadin-tabs-flow-2.0.4.jar;%APP_HOME%\lib\vaadin-text-field-flow-2.1.0.jar;%APP_HOME%\lib\vaadin-menu-bar-flow-1.0.2.jar;%APP_HOME%\lib\vaadin-upload-flow-2.1.0.jar;%APP_HOME%\lib\vaadin-context-menu-flow-3.1.2.jar;%APP_HOME%\lib\vaadin-login-flow-2.0.0.jar;%APP_HOME%\lib\vaadin-custom-field-flow-3.0.4.jar;%APP_HOME%\lib\ph-css-6.1.1.jar;%APP_HOME%\lib\ph-commons-9.1.2.jar;%APP_HOME%\lib\atmosphere-runtime-2.4.30.slf4jvaadin1.jar;%APP_HOME%\lib\slf4j-api-1.7.25.jar;%APP_HOME%\lib\logback-core-1.2.3.jar;%APP_HOME%\lib\javax.annotation-api-1.3.jar;%APP_HOME%\lib\asm-commons-7.2.jar;%APP_HOME%\lib\asm-analysis-7.2.jar;%APP_HOME%\lib\asm-tree-7.2.jar;%APP_HOME%\lib\asm-7.2.jar;%APP_HOME%\lib\javax-websocket-client-impl-9.4.27.v20200227.jar;%APP_HOME%\lib\websocket-client-9.4.27.v20200227.jar;%APP_HOME%\lib\jetty-client-9.4.27.v20200227.jar;%APP_HOME%\lib\jetty-http-9.4.27.v20200227.jar;%APP_HOME%\lib\websocket-common-9.4.27.v20200227.jar;%APP_HOME%\lib\jetty-io-9.4.27.v20200227.jar;%APP_HOME%\lib\jetty-xml-9.4.27.v20200227.jar;%APP_HOME%\lib\javax.websocket-api-1.0.jar;%APP_HOME%\lib\jetty-jndi-9.4.27.v20200227.jar;%APP_HOME%\lib\jetty-util-9.4.27.v20200227.jar;%APP_HOME%\lib\javax.websocket-client-api-1.0.jar;%APP_HOME%\lib\gwt-elemental-2.8.2.vaadin2.jar;%APP_HOME%\lib\commons-fileupload-1.3.3.jar;%APP_HOME%\lib\commons-io-2.5.jar;%APP_HOME%\lib\jsoup-1.12.1.jar;%APP_HOME%\lib\byte-buddy-1.10.1.jar;%APP_HOME%\lib\gentyref-1.2.0.vaadin1.jar;%APP_HOME%\lib\validation-api-2.0.0.Final.jar;%APP_HOME%\lib\vaadin__vaadin-mobile-drag-drop-1.0.0.jar;%APP_HOME%\lib\mobile-drag-drop-2.3.0-rc.1.jar;%APP_HOME%\lib\commons-lang3-3.0.jar;%APP_HOME%\lib\websocket-api-9.4.27.v20200227.jar
