螞蟻任務/ Hash.from_java_properties的Apache Buildr問題

Question

我有一個構建器腳本，該腳本首先加載Java屬性文件，然后創建一個Ant任務。 我收到中止錯誤：Buildr中止了！ 運行buildr時使用org / apache / tools / ant / DefaultLogger。

這是（簡化的）構建文件：

CONFIG = Hash.from_java_properties("a=1")

define "my_project", :version => "1.0" do

  ant("ant_test") do |ant_project|
    # do something
  end

end

我在OS X 10.6和Ruby 1.8.7上使用Buildr 1.3.5

堆棧跟蹤：

Answer 1

由於Buildr郵件列表上回答，您需要添加Java.load您的來電前Hash.from_java_properties所以RJB *正確初始化。

通常，這是在加載buildfile后自動完成的，但是由於在加載階段正在使用Java對象，因此需要明確告知Buildr。

（*）RJB = Ruby-Java橋

Answer 2

聽起來像是類路徑問題，但是我不能真正確定您提供的信息。 嘗試運行buildr --trace並發布完整結果。

順便說一句，但是在Buildr Users郵件列表中最容易提出和回答此類問題。
