jar

问题 I'm trying to obfuscate google play services jar with proguard. I tried two versions of the proguard config file. First one contains -keep class ** { public protected *; } And the jar stays not obfuscated. It looks ok. Second one contains -keep class com.** { public protected *; } And proguard deletes everithing. I get an error: Error: The output jar is empty. Did you specify the proper '-keep' options? Why is it empty, as the main google play services package is com.google.android.gms? 回答1:

问题 Trying to make some small changes to Apache's Velocity engine. Here's what I can and can't do. I'm making a change to the merge function(). The change I'm making doesn't matter because I haven't made it yet. ;) Right now I am settling for a println statement firing. I have two references to merge(). If I change the function to mergeBAD() Eclipse tells me that it can't find merge(). Makes sense right? I used to include in my class build path the two jars that you get when downloading velocity

问题 I have two jars are conflicted. Both of them contain a class with the same package name and class name. Due to same reasons, I cannot remove either of them. So, is there any way to resolve this issue? Ideally, I hope there is a way can let me decide the class in which jars should be invoked during runtime. I do appreciate anyone's help. 回答1: You can create a package structure (same as the one in your conflicting jars) in your project folder with a different name & copy respective contents

问题 I've done several projects and packaged them into jar files, but I've noticed that my jar files run much more slowly than in my IDE. I use Eclipse to compile and run my programs. In Eclipse, I have everything working. When I package my project as a runnable Jar and execute it by double-clicking, everything still works. But when I have animation, the program runs extremely slowly. Instead of 30 frames per second in Eclipse, I now get about 2 frames per second. The animation is very laggy.

问题 I am running Eclipse with Tomcat 5.5. My dynamic web site project includes some JAVA code that needs external jar files. Where should I place those jar files so Apache will not giving me errors such as java.lang.ClassNotFoundException ? Thanks on this. 回答1: Put them in the WEB-INF/lib of your web context, of course. If there are JDBC driver JARs in your project, you'll need to add those to the Tomcat server /lib for Tomcat 7 and higher. Those should not be in your WEB-INF/lib. 回答2: Make sure

问题 I want two seperate JAR files to be executed automatically once a docker container is called via run command, so when I type docker run mycontainer they are both called. So far, I have a dockerfile that looks like this: # base image is java:8 (ubuntu) FROM java:8 # add files to image ADD first.jar . ADD second.jar . # start on run CMD ["/usr/lib/jvm/java-8-openjdk-amd64/bin/java", "-jar", "first.jar"] CMD ["/usr/lib/jvm/java-8-openjdk-amd64/bin/java", "-jar", "second.jar"] This, however, only
