使用IntelliJ構建來自源代碼的Joda？

Question

我已經導入了Joda源代碼的maven項目（https://github.com/JodaOrg/joda-time）並試圖構建這個項目。當我這樣做，我得到以下堆棧跟蹤：在線程 「主要」 java.io.IOException的

這裏的ZoneInfoProvider類看起來像什麼：

另外值得一提的是，pom.xml文件中包含，部分執行以下操作：

 <execution> 
     <phase>compile</phase> 
     <configuration> 
      <target> 
      <property name="tz.src" value="${project.build.sourceDirectory}/org/joda/time/tz/src" /> 
      <property name="tz.dst" value="${project.build.outputDirectory}/org/joda/time/tz/data" /> 
      <!--uptodate property="tz.build.notneeded" targetfile="${tz.dst}/ZoneInfoMap" > 
       <srcfiles dir="${tz.src}" includes="**/*.*"/> 
      </uptodate--> 
      <mkdir dir="${tz.dst}" /> 
      <java classname="org.joda.time.tz.ZoneInfoCompiler" fork="true" failonerror="true"> 
       <classpath refid="maven.compile.classpath" /> 
       <sysproperty key="org.joda.time.DateTimeZone.Provider" 

值=」 org.joda.time.tz.UTCProvider「/> 運行

我不知道如何解決這個問題。有什麼建議麼？

Answer 2

這可以在案件發生，你會錯過初始化：

JodaTimeAndroid.init(this);
