我正在将现有项目从 ant 转换为 Gradle。
不幸的是,有一个 Java 类使用了 com.sun.xml.internal.bind.DatatypeConverterImpl。一方面,我将研究替换该用法,但此时我只是好奇为什么 Gradle 找不到该类,这会导致编译失败。
消息是
package com.sun.xml.internal.bind does not exist
请注意,它在 eclipse 中以及使用 javac ant 任务时编译得很好。 JAVA_HOME 设置为 1.6.0_27。
那么 Gradle 在默认情况下会导致它找不到此类的独特之处是什么?有人如何解决这个问题?
请参阅 Java 代码片段和 build.gradle 文件:
final class Test{
private static final javax.xml.bind.DatatypeConverterInterface DTC = com.sun.xml.internal.bind.DatatypeConverterImpl.theInstance;
.....
DTC.printDateTime(Calendar.getInstance());
}
apply plugin: 'java'
apply plugin: 'application'
mainClassName = "com.foo.bar.Test"
sourceCompatibility = 1.6
version = '5.4.0'
jar {
manifest {

}

最佳答案
- 解决方案 #1:
将 rt.jar 复制(而不是移动)到不同于 <JDK_install_dir>\jre\lib\rt.jar
的位置
(例如 c:\rt.jar
)并像下面这样运行你的编译器:
javac -cp c:\rt.jar your_file.java
- 解决方案#2:
使用编译器选项编译 -XDignore.symbol.file=true
