【记录】折腾Android(java)的动态编译工具：compilation-toolbox

【背景】

折腾：

【记录】在android中编译并调用编译好的java代码

的过程中，需要折腾：

http://code.google.com/p/compilation-toolbox/

去试试，Android中是否可用此库，去实现动态编译。

【折腾过程】

1.看了其介绍：

http://code.google.com/p/compilation-toolbox/wiki/GetStarted

觉得还是做得不错的，算是蛮好用的，如果可以用的话。。。

2.从：

http://code.google.com/p/compilation-toolbox/downloads/list

下载到22KB的：

compilation-toolbox-0.3.2.jar

3.加入到android项目中：

4.写测试代码：

import org.abstractmeta.toolbox.compilation.compiler.JavaSourceCompiler;
import org.abstractmeta.toolbox.compilation.compiler.impl.JavaSourceCompilerImpl;

	//http://code.google.com/p/compilation-toolbox/wiki/GetStarted
	public void testCompilationToolbox()
	{
	    JavaSourceCompiler javaSourceCompiler = new JavaSourceCompilerImpl();
	    JavaSourceCompiler.CompilationUnit compilationUnit = javaSourceCompiler.createCompilationUnit();
	    String javaSourceCode =  "package com.test.foo;\n" +
	      "public class Foo {\n" +
	      "        public static void main(String [] args) {\n" +
	      "            System.out.println(\"Hello world\");\n" +
	      "        }\n" +
	      "    }";
	    compilationUnit.addJavaSource("com.test.foo.Foo", javaSourceCode);
	    ClassLoader classLoader = javaSourceCompiler.compile(compilationUnit);
	    try {
			Class fooClass = classLoader.loadClass("com.test.foo.Foo");
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

试试结果，

结果是，执行了第一行：

JavaSourceCompiler javaSourceCompiler = new JavaSourceCompilerImpl();

结果就出现一堆的输入，显示有问题：

05-07 16:43:24.349: I/dalvikvm(1574): Could not find method javax.tools.Diagnostic.getSource, referenced from method org.abstractmeta.toolbox.compilation.compiler.impl.JavaSourceCompilerImpl.buildDiagnosticMessage

结果执行：

compilationUnit.addJavaSource("com.test.foo.Foo", javaSourceCode);

就挂了，程序就跑飞了，无法继续调试了。

5.网上搜到类似的代码：

http://compilation-toolbox.googlecode.com/svn-history/r6/trunk/src/test/java/org/abstractmeta/toolbox/compilation/compiler/impl/JavaSourceCompilerImplTest.java

所以再去试试代码：

import org.abstractmeta.toolbox.compilation.compiler.JavaSourceCompiler;
import org.abstractmeta.toolbox.compilation.compiler.impl.JavaSourceCompilerImpl;

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;


	//http://code.google.com/p/compilation-toolbox/wiki/GetStarted
	public void testCompilationToolbox() throws Exception 
	{
        JavaSourceCompiler javaSourceCompiler = new JavaSourceCompilerImpl();
        JavaSourceCompiler.CompilationUnit compilationUnit = javaSourceCompiler.createCompilationUnit();
        String javaSourceCode = "   " +
                "package com.test.foo;" +
                "public class Foo {\n" +
                "        public static void main(String [] args) {\n" +
                "            System.out.println(\"Hello world\");\n" +
                "        }\n" +
                "}";

        compilationUnit.addJavaSource("com.test.foo.Foo", javaSourceCode);
        ClassLoader classLoader = javaSourceCompiler.compile(compilationUnit);
        Class clazz = classLoader.loadClass("com.test.foo.Foo");
        //Assert.assertEquals(clazz.getName(), "com.test.foo.Foo");
        Object foo = clazz.newInstance();
        Method main = clazz.getMethod("main", String[].class);
        String args = null;
        main.invoke(foo, args);
        javaSourceCompiler.persistCompiledClasses(compilationUnit);
	}

看看结果，

结果现象和上面类似，第一行就出现类似错误。

然后后面再执行，就彻底挂了，全部log如下：

6.另外，又去：

http://compilation-toolbox.googlecode.com/svn-history/r6/trunk/src/test/java/org/abstractmeta/toolbox/compilation/compiler/impl/

看了看，有好几个测试文件的：

JavaSourceCompilerImplTest.java

SimpleClassLoaderTest.java

SimpleJavaFileManagerTest.java

TestHelper.java
