System Requirements Liquibase is designed to run with minimal hardware and software. Windows Mac Unix Linux Liquibase 4. Read the release notes 4. Just the files Download Liquibase 4. Previous Releases Access previous releases. Most of the modifications are "framework overhead" which has to be done once. The blue line is our "old System-out" statement. Don't try to run ant —you will only get lot of compiler errors.

Log4J is not on the classpath so we have to do a little work here. This is only for this project and maybe you would break other environments this is one of the most famous mistakes when working with Ant.

We introduce Log4J or to be more precise: all libraries jar-files which are somewhere under. In this example we start our application not via its Main-Class manifest-attribute, because we could not provide a jar-name and a classpath. So add our class in the red line to the already defined path and start as usual. Running ant would give after the usual compile stuff :.

For another layout Why we have used Log4J? No—all is hardcoded! But that is not the fault of Log4J—it's ours. We had coded BasicConfigurator. More comfortable would be using a property file.

In the Java source file, delete the BasicConfiguration line from the main method and the related import statement. Download a binary distribution of Ant 1. Unpack the binary distribution into a convenient location so that the Ant release resides in its own directory conventionally named apache-ant This makes the ant command line script available, which will be used to actually perform the build.

Tomcat 7. Checkout the source using SVN, selecting a tag for released version or trunk for the current development code, or download and unpack a source package. Building Tomcat involves downloading a number of libraries that it depends on. It is strongly recommended to configure download area for those libraries. You can change this see below but it must be an absolute path. It can be used to redefine any property that is present in build.

The build. You can also get most of the auxiliary JAR files i. See Optional Tasks for instructions on how to do this. The fetch. On most occasions you will not need to explicitly bootstrap Ant since the build scripts do that for you. However, if the build file you are using makes use of features not yet compiled into the bootstrapped Ant, you will need to manually bootstrap. Run bootstrap. Ant's build script will try to set executable flags for its shell scripts on Unix -like systems.

There are various reasons why the chmod task might fail like when you are running the build script as a different user than the one who installed Ant initially.

In this case you can set the Ant property chmod. The following libraries are needed in Ant's classpath if you are using the indicated feature.

Note that only one of the regexp libraries is needed for use with the mappers and Java includes a regexp implementation which Ant will find automatically. You will also need to install the particular Ant optional JAR containing the task definitions to make these tasks available. Ant has a built in diagnostics feature. If you run ant -diagnostics , Ant will look at its internal state and print it out. This code will check and print the following things.

Running ant -diagnostics is a good way to check that Ant is installed. It is also a first step towards self-diagnosis of any problem. Any configuration problem reported to the user mailing list will probably result ins someone asking you to run the command and show the results, so save time by using it yourself. For diagnostics from within IDE, use the diagnostics task to run the same tests as an Ant option.

This can be added to a diagnostics target in a build file to see what tasks are available under the IDE, what the XML parser and classpath is, etc. If you cannot get Ant installed or working, the Ant user mailing list is the best place to start with any problem. Why the user list, and not the developer list? Because there are more users than developers, so more people who can help you. Release notes of the given version in HTML format. When upgrading your Ant installation you should have a look at the Changes that could break older environments section.

ZIP archive containing the compiled version of Ant in the last released version. It is recommended that you do not download the latest version this way, as the standard way of downloading described above will redirect you to a mirror closer to you, thus making the download faster for you and reducing the load on Apache servers. ZIP archive containing the sources of Ant. If you have this you can compile Ant. If you do not have the required dependencies, the classes depending on them are just not built.

Again, it is preferred to use the standard way of getting the source package described above to make your download quicker and to reduce the load on Apache servers. Security file for checking the correctness of the zip file.

This one is the PGP signature. This one is the MD5 checksum. This one is the SHA1 checksum. This one is the SHA checksum. This directory holds the Antlibs that are made of available by the Apache Ant project.
