 @Nullable
 @Nullable StringBuilder codeLog,
 @NotNull
 @NotNull Map<String,Class<?>> parameterClasses)

Compile a class.

Parameters:

className - Class name

classBody - Class body, before update with "$CLASS_NAME$" replacement and package name prefixing

packageNameRoot - Package name prefix

codeLog - Optional "log" for final class code

parameterClasses - Generic parameters, empty if none required

Returns:

The compiled class

createEscapedJoinedString

public static String createEscapedJoinedString(String originalString)

Transform a string into the corresponding Java source code that compiles into that string. This involves escaping special characters, surrounding it with quotes, and (if the string is larger than the max string length for Java literals), splitting it into substrings and constructing a call to String.join() that combines those substrings.

createEscapedJoinedString

public static String createEscapedJoinedString(String originalString,
 int maxStringLength)

tryCompile

public static com.fishlib.base.Pair<Boolean,String> tryCompile(File basePath,
 Collection<File> javaFiles)
                                                        throws IOException

Try to compile the set of files, returning a pair of success and compiler output.

Parameters:

basePath - the base path for the java classes

javaFiles - the java source files

Returns:

a Pair of success, and the compiler output

Throws:

IOException

getJavaClassPath

public static String getJavaClassPath()

Retrieve the java class path from our existing Java class path, and IntelliJ/TeamCity environment variables.

Returns:

main

public static void main(String[] args)
