我在混合的Java/Scala項目中使用sbt。不幸的是，sbt似乎沒有對Java源進行任何依賴關係分析。例如，如果A.java取決於B.java並且我改變B.java，則它不費心重新編譯A.java。我想這是一個錯誤，但我需要一個解決方法。讓sbt重新編譯受影響的Java源代碼
唯一的解決辦法是做clear compile這很糟糕，因爲它會在IDEA項目中擦除我的javadoc和源代碼。我也嘗試打開bash並運行rm -r target/classes/，但情況更糟。 Sbt仍然沒有看到它需要重新編譯Java源代碼，只是抱怨說當我從Scala中引用它們時，這些類不存在。
是否有一種方法可以迫使sbt重新編譯所有Java源代碼？
編輯：重現：
$ git clone https://github.com/Sciss/TreeTable.git
...
$ cd TreeTable
$ git checkout 00daa4288574b658c8bb643cb2ddf9768195c50a
$ sbt compile
這將編譯該項目。 SBT會崩潰在某些點：再次

確定。現在進行編輯。
$ vi java/src/main/java/de/sciss/treetable/j/ui/TreeTableUI.java
對於管線35從DefaultTreeTableCellRenderer renderer到TreeTableCellRenderer renderer示例變化。保存並退出vi。

很明顯，這也只是重新編譯TreeTableUI.java，而實現類BasicTreeTableUI現在是腐敗，就需要重新編譯。強制重新編譯的唯一方法是清理項目。
測試用例可能是必需的。至少配置依賴項的構建定義的相關部分（包括sbt版本）很有幫助。 Java源代碼是按照依賴信息在類文件中進行增量編譯的（例如，sbt無法知道內聯常量，因爲它們不在類文件中）。增量編譯當然應該處理Java源代碼和混合項目。 –
@MarkHarrah - 我附上了一個測試用例。也許這個問題是由暫時的編譯器崩潰產生的，我不知道。如果我用'javac'編譯java源文件，它不會崩潰，所以這不是我安裝java的問題。 –
順便說一句，無關。最近幾乎在我的每個項目中，我都注意到了這個令人討厭的「解析org.fusesource.jansi＃jansi; 1.4 ...」。任何線索來自哪裏，爲什麼它檢查出5（！）次？ –
