打包成uberJar,运行后报java.net.MalformedURLException: no !/ in spec

应用使用了数据生成器扩展: Data Generator,打包成uberJar运行报错

task buildUberJar(type: CubaUberJarBuilding) {
    singleJar = true
    appProperties = ['cuba.automaticDatabaseUpdate': true]
    coreJettyEnvPath = 'modules/core/web/META-INF/jetty-env.xml'
    logbackConfigurationFile = 'etc/uber-jar-logback.xml'
}
CUBA版本为:7.1.4

错误如下:

你好,方便提供能重现问题的测试项目吗?

代码放上去了

数据库是默认的,我就添加了一个Model,按默认的生成了Screen,再安装了Data Generator,打包生成的uberJar,运行起来就报这个错。

在这里另外问一个问题,也是刚发现的,就是我用的cuba-studio今天发现生成Screen代码时,在Advanced中的出现Controoler language选择,默认是kotlin语言,之前是没有这个选项,也就是默认生成JAVA的。这里如何让他默认是生成JAVA

你好,我们已经反馈此问题,你可以关注这个帖子:

开发人员已经发布了一个新版本,你可以试试:

It seems Faker fails to initialize in uberJar due to its resource resolving issues (did not investigate yet).
I’ve just released a bugfix version 0.3.1 with temporary workaround (safe Faker initialization).

好的。晚点试一下新版本

换成0.3.1以后打包以后还是有错误,但抛出稍有些变化,还是和这个Faker有联系

方便直接在英文论坛跟帖吗?
