IndexHtmlRequestHandler#getIndexHtmlDocument: Error message improvement suggestions #311

Open CNBroderick opened 4 years ago

CNBroderick commented 4 years ago

I catch a Exception, When I download Vaadin 16 Business Starter and copy /target/index.ts(html) to fronted dir. Then run command : 

mvn jetty:run-exploded -Dvaadin.productionMode

Open browser: 127.0.0.1:8080

HTTP ERROR 500
Problem accessing /. Reason:

    Server Error

The IDEA shows Error is 

java.io.IOException: Failed to load content of 
'D:\broderick\develop\bklab\vaadin-16-business\frontendindex.html'. 
It is required to have 
'D:\broderick\develop\bklab\vaadin-16-business\frontendindex.html'
 file when using client side bootstrapping.
    at com.vaadin.flow.server.communication.IndexHtmlRequestHandler
.getIndexHtmlDocument(IndexHtmlRequestHandler.java:179)

There No file separator in 'frontendindex.html'. Should actually be '.\frontend\index.html'

Then I looking the current source code : 

    private static Document getIndexHtmlDocument(VaadinRequest request)
            throws IOException {
        String index = FrontendUtils.getIndexHtmlContent(request.getService());
        if (index != null) {
            return Jsoup.parse(index);
        }
        String frontendDir = FrontendUtils.getProjectFrontendDir(
                request.getService().getDeploymentConfiguration());

>      String message = String
>              .format("Failed to load content of '%1$sindex.html'."
>                      + "It is required to have '%1$sindex.html' file when "
>                      + "using client side bootstrapping.", frontendDir);

        throw new IOException(message);
    }

So, can there Improve to like this : 

        String message = String
                .format("Failed to load content of '%1$s%2$sindex.html'."
                        + "It is required to have '%1$s%2$sindex.html' file when "
                        + "using client side bootstrapping.", frontendDir, File.separator)
                .replaceAll("\\\\+", "\\\\")
                .replaceAll("/+", "/");

the output is 

Failed to load content of 
'D:\broderick\develop\bklab\vaadin-16-business\frontend\index.html'.
It is required to have 
'D:\broderick\develop\bklab\vaadin-16-business\frontend\index.html' 
file when using client side bootstrapping.
