Question

在Windows上使用asciidoctor-maven-plugin时，我们在执行目标进程时会遇到编码不兼容错误-asciidocs。

我们尝试使用0.1.4版本的插件和来自master的最新SNAPSHOT。

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.asciidoctor:asciidoctor-maven-plugin:1.5.0-SNAPSHOT:process-asciidoc (default-cli) on project lgtdev-doc: Execution default-cli of goal org.asciido

当使用cruby与asciidoctor gem时，我们不会收到此错误，因此可以想象问题出在jruby执行环境中。

在Mac上，我们通过设置JAVA_TOOL_OPTIONS =＆＃34; -DFile = encoding.UTF-8＆＃34;解决了同样的错误。但在Windows上这没有效果。

我们怎样才能强迫jruby使用UTF-8？

Answer 1

我们通过编辑asciidoctor-java-integration jar中的asciidoctor源解决了这个问题，强制gems / asciidoctor-0.1.4 / lib / asciidoctor.rb中的Encoding.default_external = Encoding :: UTF_8。虽然不是一个优雅的解决方案，但它有效。

在Windows上使用asciidoctor maven插件时在JRuby中强制编码
