使sbt重新编译受影响的Java源

java scala sbt

使sbt重新编译受影响的Java源,java,scala,sbt,Java,Scala,Sbt,我正在一个混合Java/Scala项目中使用sbt。不幸的是，sbt似乎没有对Java源代码进行任何依赖性分析。例如，如果A.java依赖于B.java，而我改变了B.java，它就不需要重新编译A.java。我想这是一个bug，但我需要一个解决方法 唯一的解决方案是执行清除编译，这很糟糕，因为它会在IDEA项目中删除我的javadocs和源代码。我还试图打开一个bash并运行rm-r target/classes/，但这更糟糕。Sbt仍然不认为需要重新编译Java源代码，只是在我从Scala中

我正在一个混合Java/Scala项目中使用sbt。不幸的是，sbt似乎没有对Java源代码进行任何依赖性分析。例如，如果
A.java
依赖于
B.java
，而我改变了
B.java
，它就不需要重新编译
A.java
。我想这是一个bug，但我需要一个解决方法

唯一的解决方案是执行
清除编译
，这很糟糕，因为它会在IDEA项目中删除我的javadocs和源代码。我还试图打开一个bash并运行
rm-r target/classes/
，但这更糟糕。Sbt仍然不认为需要重新编译Java源代码，只是在我从Scala中引用这些类时抱怨这些类不存在

有没有一个技巧可以迫使sbt重新编译所有Java源代码

编辑：要复制：

$ git clone https://github.com/Sciss/TreeTable.git
...
$ cd TreeTable
$ git checkout 00daa4288574b658c8bb643cb2ddf9768195c50a
$ sbt compile
这将编译该项目。sbt将在某个时刻崩溃：

嗯。现在进行编辑

$ vi java/src/main/java/de/sciss/treetable/j/ui/TreeTableUI.java
例如，将第35行中的
DefaultTreeTableCellRenderer
更改为
TreeTableCellRenderer
。保存并退出vi

再次运行编译：

$ sbt compile

显然，它只重新编译了
TreeTableUI.java
，而实现类
BasicTreeTableUI
现在已损坏，需要重新编译。强制重新编译的唯一方法是清理项目。

OP字段，该字段由0.13分支中的标记固定，现在作为sbt 0.13.2提供。

可能需要一个测试用例。至少，构建定义中配置依赖项的相关部分（包括sbt版本）是有帮助的。Java源代码是增量编译的，依赖信息在类文件中（例如，sbt不能知道内联常量，因为它们不在类文件中）。增量编译当然应该处理Java源代码和混合项目，否则。@MarkHarrah-I附带了一个测试用例。也许这个问题是由暂时的编译器崩溃造成的，我不知道。如果我使用
javac
编译java源代码，它不会崩溃，因此这不是我的java安装的问题。顺便说一句，这与我的java安装无关。我注意到这个恼人的
解析org.fusesource.jansi#jansi；1.4…
最近几乎在矿山的每个项目中。有什么线索是从哪里来的，为什么要查5次？！是的，问题在于撞车。javac成功了，但当sbt加载类文件以提取依赖信息时，Java反射失败。目前还不清楚这是Java反射还是
javac
中的错误，也可能是sbt中的错误。现在请打开sbt上的一个bug。您使用的是什么版本的Java？也许您正在以运行sbt的Java版本无法理解的格式生成类文件？啊，好吧，我确实提交了错误，对不起，我的内存是一块瑞士奶酪。
